27// MCalibrationPulseTimeCam
28//
29// Storage container for relative arrival time calibration results
30// of the whole camera.
31//
32// Individual pixels have to be cast when retrieved e.g.:
33// MCalibrationPix &avpix = (MCalibrationPix&)(*fPulseCam)[i]
34//
35// The following "calibration" constants can be retrieved from each pixel:
36// - GetTimeOffset(): The mean offset in relative times,
37// has to be added to any calculated relative time in the camera.
38// - GetTimePrecision(): The Gauss sigma of histogrammed relative arrival
39// times for the calibration run. Gives an estimate about the timing
40// resolution.
41//
42// ALL RELATIVE TIMES HAVE TO BE CALCULATED W.R.T. PIXEL IDX 1
43// (HARDWARE NUMBER: 2) !!
44//
45// Averaged values over one whole area index (e.g. inner or outer pixels for
46// the MAGIC camera), can be retrieved via:
47// MCalibrationPix &avpix = (MCalibrationPix&)fPulseCam->GetAverageArea(i)
48//
49// Averaged values over one whole camera sector can be retrieved via:
50// MCalibrationPix &avpix = (MCalibrationPix&)fPulseCam->GetAverageSector(i)
51//
52// Note the averageing has been done on an event-by-event basis. Resulting
53// Sigma's of the Gauss fit have been multiplied with the square root of the number
54// of involved pixels in order to make a direct comparison possible with the mean of
55// sigmas.
56//
57// See also: MHCalibrationPix, MHCalibrationPulseTimeCam
58//
59// The calculated values (types of GetPixelContent) are:
60//
61// Fitted values:
62// ==============
63//
64// 0: Mean Time Offset
65// 1: Error of Mean Time Offset
66// 2: Sigma of Time Offset == Time Resolution
67// 3: Error of Sigma of Time Offset
68//
69// Useful variables derived from the fit results:
70// =============================================
71//
72// 4: Returned probability of Gauss fit to Pulse. Arrival Time distribution
