26// MHCalibrationRelTimeCam
27//
28// Fills the extracted relative arrival times of MArrivalTimeCam into
29// the MHCalibrationPix-classes MHCalibrationPix for every:
30//
31// - Pixel, stored in the TObjArray's MHCalibrationCam::fHiGainArray
32// or MHCalibrationCam::fHiGainArray, respectively, depending if
33// MArrivalTimePix::IsLoGainUsed() is set.
34//
35// - Average pixel per AREA index (e.g. inner and outer for the MAGIC camera),
36// stored in the TObjArray's MHCalibrationCam::fAverageHiGainAreas and
37// MHCalibrationCam::fAverageHiGainAreas
38//
39// - Average pixel per camera SECTOR (e.g. sectors 1-6 for the MAGIC camera),
40// stored in the TObjArray's MHCalibrationCam::fAverageHiGainSectors
41// and MHCalibrationCam::fAverageHiGainSectors
42//
43// Every relative time is calculated as the difference between the individual
44// pixel arrival time and the one of pixel 1 (hardware number: 2).
45// The relative times are filled into a histogram and an array, in order to perform
46// a Fourier analysis (see MHGausEvents). The signals are moreover averaged on an
47// event-by-event basis and written into the corresponding average pixels.
48//
49// The histograms are fitted to a Gaussian, mean and sigma with its errors
50// and the fit probability are extracted. If none of these values are NaN's and
51// if the probability is bigger than MHGausEvents::fProbLimit (default: 0.5%),
52// the fit is declared valid.
53// Otherwise, the fit is repeated within ranges of the previous mean
54// +- MHCalibrationPix::fPickupLimit (default: 5) sigma (see MHCalibrationPix::RepeatFit())
55// In case this does not make the fit valid, the histogram means and RMS's are
56// taken directly (see MHCalibrationPix::BypassFit()) and the following flags are set:
57// - MBadPixelsPix::SetUncalibrated( MBadPixelsPix::kRelTimeNotFitted ) and
58// - MBadPixelsPix::SetUnsuitable( MBadPixelsPix::kUnreliableRun )
59//
60// Outliers of more than MHCalibrationPix::fPickupLimit (default: 5) sigmas
61// from the mean are counted as Pickup events (stored in MHCalibrationPix::fPickup)
62//
63// The class also fills arrays with the signal vs. event number, creates a fourier
64// spectrum (see MHGausEvents::CreateFourierSpectrum()) and investigates if the
65// projected fourier components follow an exponential distribution.
66// In case that the probability of the exponential fit is less than
67// MHGausEvents::fProbLimit (default: 0.5%), the following flags are set:
68// - MBadPixelsPix::SetUncalibrated( MBadPixelsPix::kRelTimeOscillating ) and
69// - MBadPixelsPix::SetUnsuitable( MBadPixelsPix::kUnreliableRun )
70//
71// This same procedure is performed for the average pixels.
72//
73// The following results are written into MCalibrationRelTimeCam:
74//
75// - MCalibrationPix::SetMean()
76// - MCalibrationPix::SetMeanErr()
77// - MCalibrationPix::SetSigma()
78// - MCalibrationPix::SetSigmaErr()
79// - MCalibrationPix::SetProb()
80// - MCalibrationPix::SetNumPickup()
81//
82// For all averaged areas, the fitted sigma is multiplied with the square root of
83// the number involved pixels in order to be able to compare it to the average of
84// sigmas in the camera.
