28// MHCalibrationChargeCam
29//
30// Fills the extracted signals of MExtractedSignalCam into the MH-classes:
31//
32// MHCalibrationChargeHiGainPix, MHCalibrationChargeLoGainPix for each pixel
33// and additionally for an average of the inner and the outer pixels, respectively.
34//
35// By default, subsequently the hi-gain classes are treated unless
36// more than fNumHiGainSaturationLimit (default: 1%) of the overall FADC
37// slices show saturation. In that case, the low-gain classes are treated.
38// If more than fNumLoGainSaturationLimit (default: 1%) of the overall
39// low-gain FADC slices saturate, the pixel is declared not valid and no further
40// treatment is pursued.
41//
42// The filled histograms are fitted to a Gaussian and the mean and sigma with
43// its errors and the fit probability are extracted. If none of these values are
44// NaN's and if the probability is bigger than fProbLimit (default: 0.5%), the fit
45// is declared valid. Otherwise, the fit is repeated within ranges of the previous mean
46// +- 5 sigma. In case that this does not help, the histogram means and RMS's are taken directly,
47// but the flag kFitValid is set to FALSE. Outliers of more than fPickUpLimit (default: 5) sigmas
48// from the mean are counted as PickUp events.
49//
50// Additionally, the slice number with the highest value is stored and a corresponding
51// histogram is filled. This histogram serves only for a rough cross-check if the
52// signal does not lie at the edges of chose extraction window.
53//
54// The class also fills arrays with the signal vs. event number, creates a fourier
55// spectrum out of it and investigates if the projected frequencies follow an exponential
56// distribution. In case that the probability of the exponential fit is less than
57// fProbLimit, the pixel is declared HiGainOscillating or LoGainOscillating, respectively.
58//
59// The results are written into MCalibrationChargeCam.
