27// MHCalibrationHiLoCam
28//
29// Fills the extracted high-gain low-gain charge ratios of MArrivalTimeCam into
30// the MHCalibrationPix-classes MHCalibrationPix for every:
31//
32// - Pixel, stored in the TObjArray's MHCalibrationCam::fHiGainArray
33// or MHCalibrationCam::fHiGainArray, respectively, depending if
34// MArrivalTimePix::IsLoGainUsed() is set.
35//
36// - Average pixel per AREA index (e.g. inner and outer for the MAGIC camera),
37// stored in the TObjArray's MHCalibrationCam::fAverageHiGainAreas and
38// MHCalibrationCam::fAverageHiGainAreas
39//
40// - Average pixel per camera SECTOR (e.g. sectors 1-6 for the MAGIC camera),
41// stored in the TObjArray's MHCalibrationCam::fAverageHiGainSectors
42// and MHCalibrationCam::fAverageHiGainSectors
43//
44// The histograms are fitted to a Gaussian, mean and sigma with its errors
45// and the fit probability are extracted. If none of these values are NaN's and
46// if the probability is bigger than MHGausEvents::fProbLimit (default: 0.5%),
47// the fit is declared valid.
48// Otherwise, the fit is repeated within ranges of the previous mean
49// +- MHCalibrationPix::fPickupLimit (default: 5) sigma (see MHCalibrationPix::RepeatFit())
50// In case this does not make the fit valid, the histogram means and RMS's are
51// taken directly (see MHCalibrationPix::BypassFit()) and the following flags are set:
52// - MBadPixelsPix::SetUncalibrated( MBadPixelsPix::kHiLoNotFitted ) and
53// - MBadPixelsPix::SetUnsuitable( MBadPixelsPix::kUnreliableRun )
54//
55// Outliers of more than MHCalibrationPix::fPickupLimit (default: 5) sigmas
56// from the mean are counted as Pickup events (stored in MHCalibrationPix::fPickup)
57//
58// The class also fills arrays with the signal vs. event number, creates a fourier
59// spectrum (see MHGausEvents::CreateFourierSpectrum()) and investigates if the
60// projected fourier components follow an exponential distribution.
61// In case that the probability of the exponential fit is less than
62// MHGausEvents::fProbLimit (default: 0.5%), the following flags are set:
63// - MBadPixelsPix::SetUncalibrated( MBadPixelsPix::kHiLoOscillating ) and
64// - MBadPixelsPix::SetUnsuitable( MBadPixelsPix::kUnreliableRun )
65//
66// This same procedure is performed for the average pixels.
67//
68// The following results are written into MCalibrationHiLoCam:
69//
70// - MCalibrationPix::SetMean()
71// - MCalibrationPix::SetMeanErr()
72// - MCalibrationPix::SetSigma()
73// - MCalibrationPix::SetSigmaErr()
74// - MCalibrationPix::SetProb()
75// - MCalibrationPix::SetNumPickup()
76//
77// For all averaged areas, the fitted sigma is multiplied with the square root of
78// the number involved pixels in order to be able to compare it to the average of
79// sigmas in the camera.
