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