26// MCalibrationChargeCam
27//
28// Storage container for charge calibration results from the signal distribution
29// fits (see MHCalibrationChargeCam and MHCalibrationChargePix), the calculation
30// of reduced sigmas and number of photo-electrons (this class) and conversion
31// factors sum FADC slices to photo-electrons (see MCalibrationChargeCalc)
32//
33// Individual pixels have to be cast when retrieved e.g.:
34// MCalibrationChargePix &avpix = (MCalibrationChargePix&)(*fChargeCam)[i]
35//
36// Averaged values over one whole area index (e.g. inner or outer pixels for
37// the MAGIC camera), can be retrieved via:
38// MCalibrationChargePix &avpix = (MCalibrationChargePix&)fChargeCam->GetAverageArea(i)
39//
40// Averaged values over one whole camera sector can be retrieved via:
41// MCalibrationChargePix &avpix = (MCalibrationChargePix&)fChargeCam->GetAverageSector(i)
42//
43// Note the averageing has been done on an event-by-event basis. Resulting
44// Sigma's of the Gauss fit have been multiplied with the square root of the number
45// of involved pixels in order to make a direct comparison possible with the mean of
46// sigmas.
47//
48// Final numbers of uncalibrated or unreliable pixels can be retrieved via the commands:
49// GetNumUncalibrated(aidx) and GetNumUnreliable(aidx) where aidx is the area index (0 for
50// inner and 1 for outer pixels in the MAGIC camera).
51//
52// The following "calibration" constants are used for the calibration of each pixel
53// (see MCalibrate):
54//
55// - MCalibrationQEPix::GetMeanConvFADC2Phe(): The mean conversion factor from the
56// summed FADC slices to the number of photo-electrons (in first order independent
57// on colour and intensity)
58// - MCalibrationQEPix::GetMeanFFactorFADC2Phot(): The mean F-Factor of the total
59// readout chain dividing the signal to noise of the incoming number of photons
60// (= sqrt(number photons)) by the signal to noise of the outgoing summed FADC slices
61// signal (= MCalibrationPix::GetMean() / MCalibrationChargePix::GetRSigma() )
62//
63// The following calibration constants can be retrieved directly from this class:
64//
65// - GetConversionFactorFFactor ( Int_t idx, Float_t &mean, Float_t &err, Float_t &sigma );
66//
67// where:
68// - idx is the pixel software ID
69// - "mean" is the mean conversion constant, to be multiplied with the retrieved signal
70// in order to get a calibrated number of PHOTONS.
71// - "err" is the pure statistical uncertainty about the MEAN
72// - "sigma", if mulitplied with the square root of signal, gives the approximate sigma of the
73// retrieved mean number of incident Cherenkov photons.
74//
75// Note, Conversion is ALWAYS (included the F-Factor method!) from summed FADC slices to PHOTONS.
76//
