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