28// MHCalibrationRelTimeCam
29//
30// Fills the extracted relative arrival times 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// Every relative time is calculated as the difference between the individual
46// pixel arrival time and the one of pixel 1 (hardware number: 2).
47// The relative times are filled into a histogram and an array, in order to perform
48// a Fourier analysis (see MHGausEvents). The signals are moreover averaged on an
49// event-by-event basis and written into the corresponding average pixels.
50//
51// The 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// - MHCalibrationPix::fPickupLimit (default: 5) sigma (see MHCalibrationPix::RepeatFit())
57// In case this does not make the fit valid, the histogram means and RMS's are
58// taken directly (see MHCalibrationPix::BypassFit()) and the following flags are set:
59// - MBadPixelsPix::SetUncalibrated( MBadPixelsPix::kRelTimeNotFitted ) and
60// - MBadPixelsPix::SetUnsuitable( MBadPixelsPix::kUnreliableRun )
61//
62// Outliers of more than MHCalibrationPix::fPickupLimit (default: 5) sigmas
63// from the mean are counted as Pickup events (stored in MHCalibrationPix::fPickup)
64//
65// The class also fills arrays with the signal vs. event number, creates a fourier
66// spectrum (see MHGausEvents::CreateFourierSpectrum()) and investigates if the
67// projected fourier components follow an exponential distribution.
68// In case that the probability of the exponential fit is less than
69// MHGausEvents::fProbLimit (default: 0.5%), the following flags are set:
70// - MBadPixelsPix::SetUncalibrated( MBadPixelsPix::kRelTimeOscillating ) and
71// - MBadPixelsPix::SetUnsuitable( MBadPixelsPix::kUnreliableRun )
72//
73// This same procedure is performed for the average pixels.
74//
75// The following results are written into MCalibrationRelTimeCam:
76//
77// - MCalibrationPix::SetMean()
78// - MCalibrationPix::SetMeanErr()
79// - MCalibrationPix::SetSigma()
80// - MCalibrationPix::SetSigmaErr()
81// - MCalibrationPix::SetProb()
82// - MCalibrationPix::SetNumPickup()
83//
84// For all averaged areas, the fitted sigma is multiplied with the square root of
85// the number involved pixels in order to be able to compare it to the average of
86// sigmas in the camera.
