26// //
27// MCalibrationCalc //
28// //
29// This is a task which calculates the number of photons from the FADC //
30// time slices. At the moment it integrates simply the FADC values. //
31// //
32// Input Containers: //
33// MRawEvtData //
34// //
35// Output Containers: //
36// MCalibrationCam //
37// //
38// //
39// The class MCalibrationCam hold one entry of type MCalibrationPix for //
40// every pixel. It is filled in the following way: //
41// PreParocess: MalibrationCam::InitSize(577) is called which allocates //
42// memory in an TClonesArray of type MCalibrationPix and //
43// all pointers to NULL. //
44// //
45// Process: The NULL pointer is tested on every pixel via //
46// MalibrationCam::IsPixelUsed(npix). //
47// //
48// In case, IsPixelUsed returns NULL, //
49// MalibrationCam::AddPixel(npix) is invoked which creates a //
50// new MCalibrationPix(npix) in the npix's entry //
51// of the TClonesArray. //
52// //
53// Every MCalibrationPix holds a histogram class, //
54// MHCalibrationPixel which itself hold histograms of type: //
55// HQ(npix) (distribution of summed FADC time slice entries) //
56// HT(npix) (distribution of position of maximum) //
57// HQvsN(npix) (distribution of charges vs. event number. //
58// //
59// PostProcess: All histograms HQ(npix) are fitted to a Gaussian //
60// All histograms HT(npix) are fitted to a Gaussian //
61// The histogram HBPQ (blind pixel) is fitted to a single //
62// PhE fit //
63// The histogram HBPT (blind pixel) is fitted to a Gaussian //
64// The histograms of the PIN Diode are fitted to Gaussians //
65// //
66// Fits can be excluded via the commands: //
67// MalibrationCam::SetSkipTFits() (skip all time fits) //
68// MalibrationCam::SetSkipBPFits() (skip all blind pixel fits) //
69// MalibrationCam::SetSkipPDFits() (skip all PIN Diode fits) //
