     7
     8  * MMcCalibrationUpdate.cc
     9  * MCalibrate.cc
     10  * MCalibrationPix.cc
     11  * MCalibrationPix.h
     12    - replace MCalibrationPix->IsChargeFitValid() by IsChargeValid()
     13      because we can calibrate with the histogram mean and RMS even
     14      if the fit is not OK. Thus, there is a question: IsFitted() and
     15      IsChargeValid(), i.e. does the charge make any sense?
     16
     17   * MCalibrationCam.cc
     18     MCalibrationConfig.h
     19     MCalibrationCalc.cc
     20     - found serious bug in calculation of conversion factors for the
     21       outer pixels:
     22       GetMeanConversionBlindPixelMethod and
     23       GetMeanConversionPINDiodeMethod
     24       did not correct for the area of the outer pixel, this did only
     25       MCalibrationCam::GetPixelContent which is not used by MCalibrate
