     21
     22   * manalysis/MMcCalibrationUpdate.cc,
     23     mhcalib/MHCalibrationRelTimeCam.cc:
     24     - replaced IsLoGainUsed by IsHiGainSaturated
     25
     26   * mcalib/MCalibrateData.cc:
     27     - changed the algorithm which takes either the hi- or the lo-gain
     28       such that it gives more reliable results in case of saturation
     29       and/or problems with the extraction and if no reliable
     30       result is possible the pixel is set unsuitable
     31
     32   * mcalib/MCalibrateRelTimes.cc:
     33     - removed the usage of MSignalPix::SetLoGainUsed
     34     - set the pixel to unsuitable if the arrival time could not
     35       be extracted
     36
     37   * mfilter/MFCosmics.cc, mhcalib/MHCalibrationChargeCam.cc:
     38     - replaced GetNumHiGainSaturated()>0 by IsHiGainSaturated()
     39
     40   * mhist/MHCamera.cc:
     41     - removed obsolete MMath::GaussProb from GetMedianDev
     42
     43   * msignal/MArrivalTimeCam.cc:
     44     - replaced IsValid by IsArrivalTimeValid
     45     - replaces Is[Hi,Lo]GainValid by
     46       Is[Hi,Lo]GainValid && !Is[Hi,Lo]GainSaturated in
     47       GetPixelContent
     48     - added a check for saturation in case of getting the delay
     49     - do not restrict the range of the returned delays anymore
     50
     51   * msignal/MArrivalTimePix.[h,cc]:
     52     - improved GetArrivalTime to take the hi-gain saturation
     53       better into account
     54     - added a new function IsArrivalTimeValid
     55     - removed obsolete function IsValid and IsLoGainUsed
     56
     57   * msignal/MExtractTimeAndChargeSpline.cc:
     58     - added a check to not set fMaxBinContent in case the extraction
     59       would happen in the first or last slice similar to the
     60       digital filter. This became necessary because otherwise the
     61       spline extractor sometimes extracts nonsens values
     62
     63   * msignal/MExtractedSignalCam.cc:
     64     - replaced IsValid by more accurate functions
     65     - take saturation in GetPixelContent into account
     66
     67   * msignal/MExtractedSignalPix.[h,cc]:
     68     - removed obsolete function IsValid and IsLoGainUsed
     69     - added functions Is[Hi,Lo]GainSaturated
     70
     71   * msignal/MSignalCam.cc:
     72     - removed cases 10 and 11 in GetPixelContent
     73   
     74   * msignal/MSignalPix.[h,cc]:
     75     - removed obsolete LoGainUsed references

    3838   - callisto fixed a bug which gave weird results if hi- and lo-gain
    3939     could not be extracted properly
     40
     41   - callisto: improves handling of extracted signal if lo- and/or
     42     hi-gain could not be extracted properly. If no appropriate
     43     calibration of either the signal or the arrival time is possible
     44     the pixel is now markes as unsuitable instead of estimated.
     45
     46   - callisto: Fixed a problem in the spline extraction which gave
     47     weird results if the signal was extracted from the first (and
     48     highest) slice
    4049
    4150   - callisto: Fixed a bug regarding the use of the QE which doesn't
