 *** Version 0.8

   - added all subdirectories as Include-Paths for ACLIC (s. rootlogon.C)

   - corrected 48(!) wrong entries in the Next Neighbor table of the
     Magic Camera (all in the inner part of the outer ring, mostly 
     missing a single NN)

   - Fixed a bug in the table describing the Next Neighbours of the
     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.

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

   - changed MWriteAsciiFile to accept rules (MDataChain)

   - Calls to MWriteAsciiFile::AddContainer and MWriteAsciiFile::AddRule
     must be replaced by calles to MWriteAsciiFile::AddColumn and
     MWriteAsciiFile::AddColumns. Be carefull, the arguments have slightly
     changed.

   - Implemented generalized event-matrices (one row per event)
     (MHMatrix)

   - implemented the one dimensional composite probabilities
     (MHCompProb, MCompProbCalc, comprob.C)

   - implemented the Multidimensional Distances (Next Neighbours)
     (MMultiDimDistCalc, multidimdist.C, MHMatrix)

   - Added a camera display displaying the pixel numbers to the
     event display gui.

   - Added Monte Carlo Informations to event display gui

   - Changed the camera display to display the pixel numbering
   
   - Added three buttons to the camera display to change the palette

   - Added the number of used and core pixels after image cleaning
     to MHillas

   - Changed the algorithm used in MHillas according to TDAS 02-03

   - Changed the Alpha range according to TDAS 02-03 to [-90°,90°]

   - Changed the algorithm used in MHillasSrc according to TDAS 02-03

   - Added fCosDeltaAlpha to MHillasSrc

   - The numbers of photons used to calculate fConc and fConc1 in
     MHillasExt are now scaled with the pixel size, so that one get
     a four times smaller value for the bigger pixels in the outer ring.

   - 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.



 *** 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:
     see MHillasSrc

   - 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)

   - It is now possible to write single data members of a class object to
     an output stream instead of the whole container only

   - Added a generalized filter for a data member:
     MFDataMember filter("MHillas.fWidth", '<', 0.5);

   - Added a generalized Filter parser for more difficult filter rules
     MF filter("MHillas.fWidth<0.5 && MHillas.fLength>0.5");

   - Added new Monte Carlo histograms:
     MHMcEnergyImpact and MHMcEfficiency

   - Added many new histograms needed for the flux calculation.

   - Added a generalized histograms which can fill and show up to three
     data members in either a one-, two- or three-dimensional histogram, eg:
     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.

   - Fixed a bug in the pedestals substraction

   - Introduced verbosity levels

   - Introduced a task (MReadMarsFile) which reads the RunHeader tree, too.

   - Fixed several bugs in MFTriggerLvl1 which caused to filter not to
     work correctly (thanks to Abelardo)

   - Introduced correct treatment of the diffuse Night Sky Background 
     and NSB (MMcPedestalNSB)

   - Corrected treatment of the electronic noise (MMcPedestalCopy)

   - Introduced MMcRunHeaders which contains monte carlo run informations

   - Added a 'Print'-Task (MPrint) which calls the Print function
     of a parameter container for each event

   - Removed MHtml (was replaced by THtml of root 3.02) in dohtml.C

   - 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.



 *** Version 0.5 (2001/11/06)

   - Added new GUI functionality (Analysis)

   - Added a camera display to be able to display events in the camera
     together with the calculated hillas ellipse

   - Added a 'Clone'-Task (MClone) which can clone a parameter container
     object at any state of the analysis, so that the output are several
     states

   - Fixed a bug in the collection area error calculation 
     (Thanks to Ciro and Abelardo)

   - Fixed a bug which causes merpp to crash in some environments

   - Implemented auto enabling scheme for Branches to speed up reading
     a lot (see MReadTree and MTask)

   - 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.

   - Changed the code to writer merpped (converted into root format)
     raw files, to get faster (around 10%)



 *** Version 0.4 (2001/09/20)

    - This release is made to compile on a root version >= 3.00

    - Fixed a bug which causes MReadTree to read the first file only

    - Added a task to compute the trigger rate (MMcTriggerRateCalc)
 
    - Added a task to write a container to an Ascii file (MWriteAsciiFile)

    - Added a task to write several container to a root file (MWriteRootFile)
    
    - Added calculation of the Enegry Threshold (MMcThresholdCalc)
    
    - Added calculation of the collection area (MMcCollectionAreaCalc)
    
    - fixed some bugs in the Hillas calculation
    
    - added filters to be able to control the task execution dependent on
      a parameter (for example: the number of level 1 triggers in a MC-file)

      (Remark: of the same structure)
    
    - Now we are able to display events in a first version of the
      Camera event display. To do this we must run the macro 
      "macros/readCT1.C" to read data from CT1.
