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