26// MHCalibrationChargeCam
27//
28// Fills the extracted signals of MExtractedSignalCam into the MHGausEvents-classes
29// MHCalibrationChargeHiGainPix and MHCalibrationChargeLoGainPix for every:
30//
31// - Pixel, stored in the TObjArray's MHCalibrationCam::fHiGainArray and
32// MHCalibrationCam::fLoGainArray
33//
34// - Average pixel per AREA index (e.g. inner and outer for the MAGIC camera),
35// stored in the TObjArray's MHCalibrationCam::fAverageHiGainAreas and
36// MHCalibrationCam::fAverageLoGainAreas
37//
38// - Average pixel per camera SECTOR (e.g. sectors 1-6 for the MAGIC camera),
39// stored in the TObjArray's MHCalibrationCam::fAverageHiGainSectors and
40// MHCalibrationCam::fAverageLoGainSectors
41//
42// Every signal is taken from MExtractedSignalCam and filled into a histogram and
43// an array, in order to perform a Fourier analysis (see MHGausEvents).
44// The signals are moreover averaged on an event-by-event basis and written into
45// the corresponding average pixels.
46//
47// Additionally, the (FADC slice) position of the maximum is stored in an Absolute
48// Arrival Time histogram. This histogram serves for a rough cross-check if the
49// signal does not lie at or outside the edges of the extraction window.
50//
51// The Charge histograms are fitted to a Gaussian, mean and sigma with its errors
52// and the fit probability are extracted. If none of these values are NaN's and
53// if the probability is bigger than MHGausEvents::fProbLimit (default: 0.5%),
54// the fit is declared valid.
55// Otherwise, the fit is repeated within ranges of the previous mean
56// +- MHGausEvents::fPickupLimit (default: 5) sigma (see MHGausEvents::RepeatFit())
57// In case this does not make the fit valid, the histogram means and RMS's are
58// taken directly (see MHGausEvents::BypassFit()) and the following flags are set:
59// - MBadPixelsPix::SetUncalibrated( MBadPixelsPix::kHiGainNotFitted ) or
60// - MBadPixelsPix::SetUncalibrated( MBadPixelsPix::kLoGainNotFitted ) and
61// - MBadPixelsPix::SetUnsuitable( MBadPixelsPix::kUnreliableRun )
62//
63// Outliers of more than MHGausEvents::fPickupLimit (default: 5) sigmas
64// from the mean are counted as Pickup events (stored in MHGausEvents::fPickup)
65//
66// Unless more than fNumHiGainSaturationLimit (default: 1%) of the overall FADC
67// slices show saturation, the following flag is set:
68// - MCalibrationChargePix::SetHiGainSaturation();
69// In that case, the calibration constants are derived from the low-gain results.
70//
71// If more than fNumLoGainSaturationLimit (default: 1%) of the overall
72// low-gain FADC slices saturate, the following flags are set:
73// - MBadPixelsPix::SetUncalibrated( MBadPixelsPix::kLoGainSaturation ) and
74// - MBadPixelsPix::SetUnsuitable( MBadPixelsPix::kUnsuitableRun )
75//
76// The class also fills arrays with the signal vs. event number, creates a fourier
77// spectrum and investigates if the projected fourier components follow an exponential
78// distribution. In case that the probability of the exponential fit is less than
79// MHGausEvents::fProbLimit (default: 0.5%), the following flags are set:
80// - MBadPixelsPix::SetUncalibrated( MBadPixelsPix::kHiGainOscillating ) or
81// - MBadPixelsPix::SetUncalibrated( MBadPixelsPix::kLoGainOscillating ) and
82// - MBadPixelsPix::SetUnsuitable( MBadPixelsPix::kUnreliableRun )
83//
84// This same procedure is performed for the average pixels.
85//
86// The following results are written into MCalibrationChargeCam:
87//
88// - MCalibrationPix::SetHiGainSaturation()
89// - MCalibrationPix::SetHiGainMean()
90// - MCalibrationPix::SetHiGainMeanErr()
91// - MCalibrationPix::SetHiGainSigma()
92// - MCalibrationPix::SetHiGainSigmaErr()
93// - MCalibrationPix::SetHiGainProb()
94// - MCalibrationPix::SetHiGainNumPickup()
95//
96// - MCalibrationPix::SetLoGainMean()
97// - MCalibrationPix::SetLoGainMeanErr()
98// - MCalibrationPix::SetLoGainSigma()
99// - MCalibrationPix::SetLoGainSigmaErr()
100// - MCalibrationPix::SetLoGainProb()
101// - MCalibrationPix::SetLoGainNumPickup()
102//
103// - MCalibrationChargePix::SetAbsTimeMean()
104// - MCalibrationChargePix::SetAbsTimeRms()
105//
106// For all averaged areas, the fitted sigma is multiplied with the square root of
107// the number involved pixels in order to be able to compare it to the average of
108// sigmas in the camera.
