 *** Version 0.9.3 (2005/06/03)

   - general: MMcEvt now derived from MMcEvtBasic which should 
     have no influence on compatibility with older camera files

   - general: Implemented a new option to MReadReports which allows
     to force reading of the first event of some trees (eg. Drive-tree)
     before any other tree.

   - general: Made a fix to MPointingPosCalc which assumes that the
     run-type is real-data if Process is called before ReInit, such
     that also the very first Drive-events in a run are treated 
     correctly.

   - shoplot now displays the filename in the title bar of the window

   - merpp: new options: --auto-time-start --auto-time-stop which
     allow to cut updating with slow-control at the start- or 
     (previousle --auto-time only allowed: and) stop-time of
     the run stored in the runheader.

   - callisto: changed default of fgFallTimeHiGain in 
     MExtractTimeAndChargeSpline from 1.5 to 0.5. 0.5 was
     already set as default in callisto_Dec04Jan05.rc

   - callisto: the digital filter (MExtractTimeAndChargeDigitalFilter)
     now changes the filename for new weights automatically for
     cosmics, MC and for different calibration colors.

   - callisto: a problem with the order of some code cause the
     name of the weights file in MPedestalY2 to be ignored.
     Wrongly the calibration_UV weights were used instead
     of the cosmics weights set in callisto.rc.

   - callisto: should allow ct1 pulser data when the color is
     explicitly set also for pretty new runs

   - callisto: a new option (MCalibrateData.ScaleFactor) allows
     to introduce an additional scale factor (should be around 1)
     to adapt for slight deviations in different extractors from
     the MC calibration. For MC calibrations the scale factor
     is fixed to 1

   - callisto: MFCosmics should handle very high signals a bit
     more accurate now

   - callisto: when calculating the mean pedestal rms for different
     pixel sizes or sectors also kUnsuitableEvt is now taken into
     account - not only kUnsuitableRun

   - callisto: '-raw' option is now the default
   
   - callisto: A dead pixel check has been implemented in MJPedestalC2.
     This has the advantage that mean values in the calibration (eg
     arrival times) are calculated more accuratly.

   - callisto: In the resource file callisto_Dec04Jan05.rc
     MJPedestalY2.ExtractWinRight has been reduced from 4.0 to 2.0

   - callisto: new Hi-/Lo-Gain intercalibration constants
     hilocalib_sp1.root and hilocalib_sp1_mc.root

   - callisto: changed default for MJPedestalY2.MaxEvents
     from 2000 to 5000 like in callisto_Dec04Jan05.txt

   - callisto: in MCalibrationChargeCalc the limit fgPheErrLowerLimit
     has changed from 9.0 to 6.0. This is necessary to exclude two very
     ringing pixels in September which - when kept - destroy the image
     cleaning around them (Markus G.)

   - callisto: (!) The Muon analysis of all data taken so far has
     suggested that different extractors give slightly different
     absolute results after calibration, due to there different
     handling of the calibration- and cosmics pulse shape. Although
     the over all calibration seems to be a bit to pesimistic (or 
     the MC seems to be a little bit - 3-5% - too much attenuated).
     There for correction factors have been introduced which correct
     the calibration constants by
         0.956937799 for Digital Filter (callisto.rc)
     and
         0.904159132 for Spline (callisto_Dec04Jan05.rc)
     calibration. The main advantage is, that both data types can
     be easily analysed together and compared to the same MC sample.
     The factors are choosen such, that the reference is now a 
     Monte Carlo sample calibrated with Digital Filter (callisto.rc)

   - star: fixed a bug which caused the first bin of the histograms
     vs time to disapear in PostProcess. This gave wrong results
     on the screen. The output and all following programs not
     directly accessing the histograms haven't been affected

   - star, ganymed: Made sure that always the first Drive-tree event
     is read and Processed before the first data event was read.

   - ganymed: implemented the possibility to replace the standard 
     false source plot with a different one. For example: If
     you want to use a Disp based FS plot use the resource:
       NameHistFS: MHDisp
     For details about the requirements of these plots look
     at the corresponding classes

   - MJOptimize: For On/Off and Wobble optimization MJOptimize
     has been replaced by MJOptimizeCuts. To use MHThetaSq instead
     of MHAlpha call MJOptimizeCuts("MHThetaSq"). Make sure in this
     case MAlphaFitter is setup correctly. For On-Only optimization
     MJOptimize has been Replaced by MJOptimizeCuts, too. Call
     RunOn() instead of Run(). For energy estimation MJOptimize
     has been replaced by MJOptimizeEnergy

   - sponde: The input MC spectrum can now be weighted to fake a
     different spectrum. This is done via MMcSpectrumWeight. For
     more details see the class description and sponde.rc

   - sponde: The paremeter comparsion plots are not scaled by
     their entries anymore. Instead the MC plot is scaled by using
     the result spectrum of the analysis. If the input MC spectrum
     and the result spectrum has different slopes the absolut 
     normalization is normally wrong.



 *** Version 0.9.2 (2005/05/20)

   - general: Changed the default paths for calibrated data and image
     files. (The implemented access to these files doesn't yet exist)

   - general: support for MRunIter has been removed from the job classes
     (use the setter functions of MSeqeunce instead)

   - general: ProcessFile has been renamed to Process in all job classes,
     because ProcessFile is missleading

   - general: The storage of the palette in MHCamera is now possible

   - general: new bits describing unsuitable and unreliable pixels have
     been introduced in MBadPixelsPix: kPreviouslyExcluded, 
     kDeadPedestalRms, kFluctuatingArrivalTimes

   - general: fixed reading of CC-REPORTS (weather data) for Arehucas file
     versions newer than V200404070 

   - general: support for cc file versions newer than V200504130. Added
     support for active loads (MCameraActiveLoad) and central pixel
     (MCameraCentralPixel)

   - general: added new histograms for image parameters versus size
     (MHVsSize)

   - general: The eventloop now automatically calls PrintStatistics

   - Status Display: Improved support for printing:
     + A default can now be set in .rootrc (for more details see 
       MStatusDisplay::PrintPS)
     + A print dialog is opened so that printer and command line
       can be canged

   - showlog: improved such that it handles different verbosity levels
     more accurate now. This mean you can suppress output when
     using showlog.

   - showplot: improved
     + The new graphics formats have been implemented 
       (pdf, svg, png, jpg and xpm)
     + Implemented an interface for printing. Because you can change
       the printing command from the command line you can use all
       the nice postscript tool. To print a booklet for example call: 
       showplot -b --print --print-cmd="cat %f" filename.root | lpr
       showplot -b --print --print-cmd="psbook %f | psnup -2 | lpr" filename.root
       showplot -b --null --print --print-cmd="psbook %f" filename.root > book.ps

   - callisto: fixed a bug in the recognition of the calibration bit
     pattern. Concerns only intensity calibration. (The strength of the 
     intensity has been updated in some cases)

   - callisto: add a filter against PIN Diode events when running over
     calibration runs since some of the recent calibration runs have
     been taken with Pin Diode.

   - callisto: added support for the runs 39942, 39944, 44834, 39941,
     39943, 44833 in the calibration (MCalibColorSet)

   - callisto: MJCalibration.MHCalibrationChargeCam.ProbLimit has
     been set to 1e-18 in callisto_Dec04_Jan05.rc

   - callisto: in callisto_Dec04Jan05.rc: set value for 
     MJPedestalY2.MaxEvents from 2000 to 5000 to get better 
     statistics for the calculation of the mean pulse time 
     of the cosmisc
       
   - callisto: the charge limit in the calibration has been raised 
     from 2.5 to 4.5

   - callisto: new setup read from callisto.rc
     + MCalibCalcFromPast.fNumEventsDump
     + MHCalibrationChargeCam.NumHiGainSaturationLimit
     + MHCalibrationChargeCam.NumLoGainSaturationLimit

   - callisto: MExtractTimeAndChargeSpline extractor:
     + The integration ranges were shifted by 0.2 FADC slices to the right. 
     + unreliable handling of floating point values caused different
       results on different platform or with different compiler options:
       The new algorithm is numerically exact and more accurate because
       it doesn't calculate the integration position by multiple times
       adding the step-size (which results in numerical uncertanties
       exspecially if multiplied with large numbers)
     + A lot of fixes have been introduced which effects integrating the
       spline at the edges of the valid range. In this case any memory
       was randomly accessed. This behaviour can be tested replacing
       all MArrayF by TArrayF which perform a range check (but of course
       they are a lot slower)
     ! No result obtained with the Spline before can be trusted! Due to
       random memory access it might by completely random!

   - callisto: set new defaults in MExtractTimeAndChargeDigitalFilter:
     + extraction range in the high gain to 4.
     + weights file to cosmics_weights46.dat

   - callisto:
     + introduce the check for fluctuating arrival times.
     + set charge limit to from 2.5 to 4.5
     + introduce asymmetric exclusion due to "deviating number of phes":
       Default: -9.0 +4.5
     + make deviating number of phes unsuitable (see David's findings).

   - callisto: fixed the display of unsuitable pixels. The old change
     to a real profile in MHCamera broke it.

   - callisto: The cosmics filter is used in MJCalibration now 
     independant of the pulser color (formaly it was used only for 
     CT1-pulser data). The threshold of number of max empty pixels 
     has been raised from 2% to 5% in MJCalibration. The maximum
     fraction of rejected event is 50% otherwise the calibration has
     failed. The filter now ignores unsuitable pixels.
     Setup the filter from callisto.rc using "ContCosmics"
     (see MFCosmics::ReadEnv)

   - callisto: changed default for fgOffsetFromLogain back
     from -2.8 to -1.8 in digital filter. 

   - callisto: for the common extractors 
      + MExtractFixedWindow
      * MExtractTimeAndChargeSlidingWindow
      * MExtractTimeAndChargeSpline
      * MExtractTimeAndChargeDigitalFilter
     the hi- and lo-gain reolution is stored in fResolutionPerPheHiGain
     and fResolutionPerPheLoGain

   - callisto: Updated the hi-/lo-gain intercalibration constants
     hilocalib_sp1.root, hilocalib_df46_mc.root, hilocalib_df4.root, 
     hilocalib_df6.root

   - callisto: The default lo-gain extraction window for the
     MExtractTimeAndChargeSlidingWindow extractor has been increased 
     from 6 to 8 to take the stretch of the pusle into account

   - callisto (!!!): fixed an important bug in the setting of the 
     incoming pedestal pointer to the signal extractor extracting
     pedestals. This bug caused the pedestals not to be subtracted 
     correctly in the calibration afterwards. The effect was about 10% 
     too high conversion factors for the digital filter and the spline
     and more than 40% for the sliding window. 
     The bug existed since end of February! (Markus G.)

   - star: added muon support to star. A new tab "MHMuonPar" is
     displayed. The lower right plot is an estimate of the point spread
     function. A reference value is displayed. To get the real PSF
     you must compare with MC. The setup for the muon analysis
     is done in star.rc. More informations can be found in
     MHSingleMuon and MHCalibParCalc

   - star: The weather data is now displayed in star

   - star: MEventRateCalc handles the calculation of the event rate more
     accurate now in case of the start of a new run inside a sequence

   - ganymed: a bug in MSrcPosCalc has been fixed (The changes were taken
     from a bugfix of Wolfgang to Loc0LocToCam; Wolfgang: the results are
     changed only minimally

   - ganymed: (MJCut and MJOptimize) now displayes the number of 
     excess events versus size. The energy estimation is done in
     MJSpectrum (sponde)

   - ganymed: got support for using other variables than Alpha, eg. Theta.
     Therefor you need a class deriving from MHAlpha which supports
     this variable (one is already existing: MHTheta, which is now the
     default in ganymed). It is setup through ganymed.rc

   - added a full featured spectrum program (sponde) which reads
     ganymed output and monte carlos and compiles a spectrum



 *** Version 0.9.1 (2005/04/14)

   - Fix bug on the arrival time reconstruction when using Digital
     Filter (in some marginal cases (10%) times were reconstructed shifted
     by 0.2 slices)

   - all executables now return 2 where in previous versions -1 has
     been returned (gave problems with shell-scripts)

   - the Hi-/Lo-Gain intercalibration for monte carlo files is now
     also done with a intercalibration input file

   - a bug in the time fine adjustment of the digital filter has been fixed

   - a lot of small fixes to calling TPad::Divide with a margin==0

   - MStatusDisplay now shows the memory usage

   - added a memory leak statistic after the eventloop

   - MHadronness replaced by MParameterD

   - MEnergyEst replaced by MParameterD

   - wobble mode can now be switched on from the data-set

   - switched on bad pixel detection for a pedestal level
     which is more than 5 times the variance

   - Fixed default paths to be correct for the new data center

   - Fixed handling of drive data. The pointing position in now
     copied to MPointingPos inside star for real and MC events

   - made sure, that the sequences in a dataset are sorted by
     their number to ensure the correct synchronization

   - added all resource files necessary to handle spline extraction
     of signal for the late 2004 and the early 2005 data

   - update the reference lines for the december data

   - changed default for fgHiGainFirst from 2 to 0 in spline extractor
     This is important for the Dec. and Jan. data where the calibration
     pulse position changes much.

   - changed default for fgOffsetFromLogain from -1.8 to -2.8 in digital
     filter. This corrects only an defective extraction of the MC at 
     low-gain signals lower than 90 phes.

   - fixed some slowdown in calibrating data with interleaved events from
     Jan and Dec. As a workaround made the pretty palette the default. 
     The inverse Deep Blue Sea has a bug which slows down long calibration
     runs a lot.

   - implemented new values from new starguider report as defined
     in TDAS00-07 V7.1 (eg SkyBrighness)

   - Fixed the formerly wrong unit of azimuth and zenith angle deviation
     in starguider report (If you merpp the same reports with this version
     you'll get the correct units (arcmin) but a different result
     than with old versions (wrong units))

   - Now the status display can also write PNG, JPEG and XPM (other file
     formats are still unsupported by root)

   - added a lot of scripts and macros in directory datacenter used
     for automatic processing



 *** Version 0.9 (2005/03/23)
   
   - Calibration is now done autmatically into photo-electrons like 
     decided by the Collaboration Board
 
   - Reference lines in the display can be read from resource file

   - callisto can now run with three data types: rawdata, rootdata, MC

   - added two classes mreport/MReportStarguider.cc and 
     mreport/MReportStarguider.h for implementing starguider-data
     
   - the output of merpp-update now contains starguider information:
     MReportStarguider and MTimeStarguider
   
   - Fixed bug in MHHadronness.cc which made that the displayed Q-factor 
     values were lower than they should. This was more visible for high
     energy (Size) events.

   - Made MExtractTimeAndChargeDigitalFilter the default for callisto

   - added a new loop to callisto to support the correct extraction of 
     the pedestal and pedestal rms through the signal extractor

   - added class to perform fourier tranformation of a hexagonal structure
     (MHexagonalFT)

   - added class to perform fourier tranformation of a hexagonal structure
     in a tasklist (MHexagonalFTCalc) example: hft.C

   - added class to enhance the MCerPhotEvt from the Magic camera geometry
     MGeomCamMagic to a enhanced geometry MGeomCamMagicXT having only
     small pixels, example: extendcam.C

   - added possibility to write data to memory (TTree) using MWriteRootFile

   - added possibility to read a TTree stored only in memory by MReadTree

   - new classes to deal with the interleaved calibration events:
     MTriggerPattern, MTriggerPatternDecode and MFTriggerPattern

   - implemented filters to callisto to skip calibration events

   - changed callisto to calculate three kinds of pedestals and pedestal rms:
     + fundamental pedestal (MPedPhotFundamental): extracted directly from
       the slices by statistics                              
     + pedestal from extractor (MPedPhotFromExtractor): extracted with the
       signal extractor without randomization
     + random pedestal from extractor (MPedPhotFromExtractorRndm): extracted
       with the signal extractor with randomization (extraction window is 
       randomly fixed)
     The three kind of pedestal is not yet implemented (for speed reasons) as
     long as nobody really needs it:
     + pedestal from extractor with randomizatiuon (MPedPhotFromExtractorRndm): 
       extracted with the signal extractor with randomization

    - callisto now finds the pulse position in the data automatically

    - implemented data reduction in calibrated data by reducing the precision
      of the stored floating point values (pedestal, rms and signal) to
      roughly 0.5%

    - fixed showplot to make file format conversion (eg. converting a
      status display stored in a root file into a postscript file) in
      batch mode possible:
      showplot -b --save-as-ps[=outfile.ps] infile.root

    - Allow class names as part of filter rules, eg
      (MFSupercuts) && (MHillas.fSize>100)

    - fixed a lot of stuff to allow all programs to process MonteCarlo
      camera files.

    - enhanced possibility to debug reading of resource file

    - MDataChain should handle priorities of operator more 
      accurate now

    - completely revised the container in which the signal is stored
      MCerPhotEvt/Pix, MArrivalTime --> MSignalCam/Pix
       * the new implementation is faster and
       * needs less storage space

    - FIRST version which can process Monte Carlos through the 
      whole chain of programs (callisto, star, etc)

    - implemented new image parameters for the border length of
      the shower image (MNewImagePar2)

    - implemented wobble-mode in ganymed

    - new class (MJOptimize) taking care of all optimization processes



 *** Version 0.8.6 (2004/10/05)

   - New combined signal and time extractor 
     MExtractTimeAndChargeDigitalFilter

   - The Report for the trigger section in the CC run summary has been
     updated, and now the IPRs (Individual Pixel Rates) are available.

   - new macros for database interaction: filldotrun.C, filldotrbk.C

   - added new program which can convert colored output which was redirected
     into a file back into colored text (for example to display it with
     more): showlog

   - added new program to display an MStatusArray of plots (stored with
     MStatusDisplay) from a file: showplot

   - Added support for Sequences (MSequence). Sequences are blocks of run
     files containing the same calibration and belonging to the same 
     source

   - Added a new task (MTaskEnv) which can be used in setup files to switch
     between different tasks (for example to choose a signal extractor)

   - Implemented automatic file splitting in MWriteRootFile

   - After image cleaning an island index is assigned to all used pixels.
     The index corresponds to the order of the islands in size.

   - added a cleaning which takes signal height _and_ arrival time into
     account: probability cleaning (for more details see MImgCleanStd)

   - added a cleaning which takes takes the absolute number of photons
     times the area ratio as cleaning level 
     (for more details see MImgCleanStd)

   - Changed calculation of image parameters such, that it can be done
     for all used pixels or the pixels with a defined island index only

   - implemented new image parameters displaying the number of islands,
     saturated hi-gain and lo-gain pixels (MImagePar, MHImagePar)

   - event display in executable changed to support also calibrated files
     (done with MJCalibrateSignal)

   - added program doing the calibration and the signal extraction
     and signal calibration: callisto Most part of the setup is done
     by a resource file: callisto.rc

   - implemented support for pixels with negative IDs (Raw file format
     version 4)

   - implemented an new option in merpp (--auto-time) to get the time
     range for cc and/or caco data from the run header of the raw data

     Camera Display by a resource file: mars.rc

   - The the mars-executable Camera Display can now also read
     calibrated data files written by callisto/MJCalibrateSignal

   - Added a new class which can calculate the source position in
     the camera from a pointing model known to be correct and
     the pointing model used for observations (MSrcPosFromModel)

   - added a new version of the class calculating the effective on-time
     MHEffectiveOnTime. It unifies the old classes MHEffOnTime, 
     MHEffOnTimeTime, MHEffOnTimeTheta, MHTimeDiff, MHTimeDiffTime and
     MHTimeDiffTheta.

   - added the possibility to count how often a signal is above (or 
     below) a certain threshold in MHCamEvent and MHCamEventRot (this
     can replace MHTriggerLvl0)

   - added ore convinient ways to set the axis-titles of your histograms
     in your macro to some MH-classes like: MH3, MHVsTime, MHSectorVsTime,
     MHPixVsTime, MHVsTime, MHCamEvent and MHCamEventRot



 *** Version 0.8.5 (2004/08/06)
 
   - new Signal Extractors: MExtractFixedWindowSpline 
     and MExtractAmplitudeSpline

   - implementes interleave in merpp to be able to merpp parts of a file

   - implemented force-functionality to merpp

   - star display to display star catalogs (MAstroCatalog)

   - star display to 'mirror' stars to the camera (MAstroCamera)

   - implemented a new cleaning option which allows cleaning scaled with
     the real ratio of the rms depending on the pixel size, not only the
     square root of the pixelsize (MImgCleanStd, MCameraData)

   - removed obsolete MBlind* classes

   - Signal extractor taking the AB flag into account implemented (this makes
     an odd number of slices for signal extraction possible
     (MExtractSignalABcorr)

   - implemented a class extracting the pedestal from the raw-data (events)
     itself using empty lo-gain (MpedCalcFromLoGain)

   - Added mean values to MPedPhotCam

   - Added Makefile for Darwin (this OS is NOT officially supported!)



 *** Version 0.8.4 (2004/04/19)

   - new fast arrival time extractor using cubic splines: 
     MExtractTimeFastSpline

   - implementes multi-argument support in MDataChain
     ("pow(a, b)")

   - implemented double reference support in MDataChain
     ("MCameraLV.fPowerSupplyA.fVoltagePos5V")

   - added support in MF for expressiond like 
     "MHillas.fWidth<2*<MHillas.fLength"

   - MDataChain is now able to support variables like [0], [1], ...
     which can be used in fit functions as parameters. The interface
     is implemented through the new virtual function 
     MParContainer::SetVariables

   - added new class MArrivalTimeCam/MArrivalTimePix:
     Storage containers to hold the ArrivalTime of the camera/pixel

   - added new classes for the calibration of relative arrival times:
     MCalibrationRelTimePix and MCalibrationRelTimeCam
  
   - added new classes to extract the signal of the blind pixel and the 
     PIN Diode separately: MExtractBlindPixel and MExtractPINDiode

   - added new classes for the bad-pixels treatment (MBadPixels*)
     which are more powerfull than the old ones (MBlindPixel*)
     and will replace them.

   - added filter against cosmics: MFCosmics

   - added new class MArrivalTimeCalc2:
     Calculates the arrival time as the signal weighted mean of the time 
     slices in the maximum window

   - added a new macro call pointspreadfucntion.C that fits with a 2D 
     gaussian the DC spot for an star. It gives you the RMS of
     the PSF and the center of the star, very useful for misspointing 
     studies.

   - added support for multi-telescope camera files. Added classes 
     MStereoCalc and MStereoPar, classes to calculate and store shower
     parameters calculated from the data of two telescopes, for the MC
     studies regarding the MAGIC clone.

   - added MMcCalibrationCalc, MMcCalibrationUpdate, classes to obtain
     MC data calibrated in photons instead of ADC counts.

   - added three macros to show the calibration and analysis chain of 
     MC data. The macro starmc.C does both calibration and analysis, producing
     an output containing Hillas parameters for each event. The macro 
     mccalibrate.C does just the calibration and writes out a file containing
     pixel information in photons instead of FADC data. The macro starmc2.C
     reads in such a file and produces an output with Hillas parameters.

     + MJExtractSignal
     Note: All of them are preliminary!

   - Added Iterator to iterate over files giving only the run-number

   - Added class (MHSectorVsTime) and example (sectorvstime.C) to plot
     the evolution of a sector vs time

     of time (readrep.C)

   - Added a generalized histogram (similar to MH3) called MVsTime
     which allows to plot variables (or rules - MDataChain - of
     variables) vs time. For an example have a look at tempvstime.C.

   - Changed the name of the event trees:
       + Events    --> Events
       + PedEvents --> Pedestals
       + CalEvents --> Calibration

  - changed name of MTime in the event trees from MRawEvtTime to MTime

     of histograms while an eventloop is running (MStatusDisplay,
     an example can be found at status.C)

   - reorganized directories:
     classes describing the image              --> mimage

       + moved fConc, fConc1 from MHillasSrc to MNewImagePar
       + moved fNumUsedPix, fNumCorePix from MHillas to MNewImagePar
       + MHillasExt now derives from MParContainer instead of MHillas
     --> Files written with the old definition are more or less unreadable

   - reading of reflector files

   - display data from reflector files in the camera

   - implemented currents (and display them in the camera)

   - logarithmic scale in camera

     CT1 camera (a pixel 127 doesn't exist and the pixel 126 didn't
     have any neighbour)

   - changed trigrate.C: now it calculates the pure NSB triggers from
     a camera file (generated with no showers), so there is no need
     to introduce them by hand in the BgR array (for more details
     please ask Abelardo)

   - added MHHadronness (and MHadronness) as a general facility to evaluate
     the quality of a gamma-hadron seperation method

   - added new task to smooth the camera contents (MCameraSmooth)

   - added possibility to use interpolated pixel values for blind pixels
     instead of removing it completely from the analysis

   - Implemented the possibility to save the whole eventloop with
     its setup to a file. This information can be read and from
     it you can (re)create a Macro. See MEvtLoop::Read, MEvtLoop::Write
     and MEvtLoop::MakeMacro. If you find something not working, please
     report - this stuff is still in a beta phase.

   - MBlindPixelCalc set all Ceta-Tauri pixels to unused not only for the
     file having crab starfield, but also for all following files - fixed

     MMcCorsikaRunHeader, MGeomPMT, MGeomMirror)



 *** Version 0.7 (2002/04/30)
 
   - added a bugfix to MCerPhotCalc. In older camera versions (<=40)
     the pedestal mean value was saved incorrectly. For files from
     this versions we substract 0.5 from the pedestal mean.
     WARNING: This may effect your results, so don't wonder...

   - First implementation of an algorithm using only triggered events
     for the collection area calculation

   - Ascii Output can now also be used for parameter containers which
     doesn't overload MParCointainer::AsciiWrite

   - The Ascii Output is now also capable of writing single data members
     of one container

   - You are now able to change the order of the values written to the
     ascii file

   - You can now specify a conversion factor for each data member written
     to an ascii file. This may be usefull to change the units of the 
     data member (eg. degrees instead of millimeters in case of the 
     hillas parameters)

   - Replaced old MHillas by a new structure which allows you to extend
     the parameters stored in MHillas very easily:
     see MHillas and MHillasExt

   - Added classes to handle source dependancy of image parameters:

   - Added container (MBinning) to have a standard input for the binning
     in different histograms (eg. the Energy bins should be the same in
     all histograms)

   - Changed Hillas histograms from mm to deg

   - Added the flexible binning to the hillas histograms

   - Added a filter for the alpha parameter (MFAlpha)

     MH3 mh3("MHillas.fWidth", "MHillas.fLength");

   - Added:
       * calculation of <Theta> as a function of Theta (MHThetabarTheta)
       * calculation of <Theta> as a function of time (MHThetabarTime)
     they are needed in the flux calculation in 
     order to select for a given bin in Theta (or time) the appropriate 
     effective collection area, which is assumed to be given as a function 
     of Theta and the true energy

   - Added calculation of the migration matrix in the energy 
     (MHMcEnergyMigration):
     the migration matrix describes the migration from the true (E_true)
     to the estimated energy (E_est); it is needed to determine the
     distribution of E_true from the measured distribution of E_est 
     by unfolding

   - changed the color palette in the camera display to DeapSea.



 *** Version 0.6 (2002/01/15)

   - Introduce the option of disable pixels (MBlindPixels and
     MBlindPixelCalc) for the analysis (eg MHillasCalc) to be 
     able to deal with Star Field NSB.

   - changes to be more efficient with root 3.02/06

   - root 3.02/06 fixes:
     + the memory leak when reading MRawEvtData
     + loosing more time than necessary to update the progress bar

   - MWriteAsciiFile is now capable of writing more than one container
     in a line. For example: To be able to write Monte Carlo and 
     Hillas values (energy and alpha) in one line.

   - Fixed a bug in the Histogram classes which caused histograms to
     be written to a file by MWriteRootFile without request

   - changed the object I/O from the old stylish root I/O to the new
     'auto evolution scheme' This was done only for classes which are not
     yet used in Monte Carlo files, so that these files are still readable.

   - Added support for a progress bar in MEvtLoop and MReadTree 
     (see the Analysis Window in Mars for an example)

   - Fixed a bug in the package creation which disturbed the conversion
     between a mars version unpacked from a tar file and the repository.
