     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

     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

   - 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

     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

     the energy spectrum of a monte carlo file

       + 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)

     the parameters stored in MHillas very easily:
     see MHillas and MHillasExt

       * 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)

     + 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

   - 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.
