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	//
