      - changed/fixed the input name of the MPedPhotCam used in the
        image cleaning
+
+   * mraw/MRawFileRead.[h,cc]:
+     - changed return type of OpenNextFile
+     - in some cases return kERROR in OpenNextFile to abort the Processing
+       with an error
+
+   * mraw/MRawRunHeader.cc:
+     - call a wrong file format version ERROR now
+
+   * mhflux/MAlphaFitter.[h,cc]:
+     - make sure that resetted values are returned if fit failed
+     - set default scaling too kOffRegion
+
+   * mhflux/MHAlpha.cc:
+     - some small fixes to handling of MHAlphaOff
+
+   * mhflux/MHFalseSource.[h,cc]:
+     - implemented possible usage of MHFalsSourceOff for On-Off-Analysis
+     - updated display accordingly
+     - updated fit accordingly
+     - removed catalog temporarily from plots until I found the
+       reason for the strange crashes
+
+   * mbadpixels/MBadPixelCalc.[h,cc]:
+     - implemented the possibility to check the pedestal rms against the
+       variance of the pedstal rms, too. The option is curretly switched
+       off.
+     - enahanced informal output in PreProcess
