    6060     MJPedestalY2.ExtractWinRight has been reduced from 4.0 to 2.0

     62   - callisto: in MCalibrationChargeCalc the limit fgPheErrLowerLimit
    6363     has changed from 9.0 to 6.0. This is necessary to exclude two very
    6464     ringing pixels in September which - when kept - destroy the image
    6565     cleaning around them (Markus G.)

     67   - callisto: (!) The Muon analysis of all data taken so far has
     68     suggested that different extractors give slightly different
     69     absolute results after calibration, due to there different
     70     handling of the calibration- and cosmics pulse shape. Although
     71     the over all calibration seems to be a bit to pesimistic (or
     72     the MC seems to be a little bit - 3-5% - too much attenuated).
     73     There for correction factors have been introduced which correct
     74     the calibration constants by
     75         0.956937799 for Digital Filter (callisto.rc)
     76     and
     77         0.904159132 for Spline (callisto_Dec04Jan05.rc)
     78     calibration. The main advantage is, that both data types can
     79     be easily analysed together and compared to the same MC sample.
     80     The factors are choosen such, that the reference is now a
     81     Monte Carlo sample calibrated with Digital Filter (callisto.rc)
