34// MCalibrateData
35//
36// This task takes the integrated charge from MExtractedSignal and applies
37// the calibration constants from MCalibrationCam to convert the summed FADC
38// slices into photons. The number of photons obtained is stored in MSignalCam.
39// Optionally, the calibration of pedestals from an MPedestalCam container into
40// an MPedPhotCam container can be chosen with the member functions
41// SetPedestalType(). Default is 'kRun', i.e. calibration of pedestals from a
42// dedicated pedestal run.
43// In case, the chosen pedestal type is kRun or kEvent, in ReInit() the MPedPhotCam
44// container is filled using the information from MPedestalCam, MExtractedSignalCam,
45// MCalibrationChargeCam and MCalibrationQECam
46//
47// Selection of different calibration methods is allowed through the
48// SetCalibrationMode() member function (default: kFfactor)
49//
50// The calibration modes which exclude non-valid pixels are the following:
51//
52// kFfactor: calibrates using the F-Factor method
53// kBlindpixel: calibrates using the BlindPixel method
54// kBlindpixel: calibrates using the BlindPixel method
55// kFlatCharge: perform a charge flat-flatfielding. Outer pixels are area-corrected.
56// kDummy: calibrates with fixed conversion factors of 1 and errors of 0.
57//
58// The calibration modes which include all pixels regardless of their validity is:
59//
60// kNone: calibrates with fixed conversion factors of 1 and errors of 0.
61//
62// Use the kDummy and kNone methods ONLY FOR DEBUGGING!
63//
64//
65// This class can calibrate data and/or pedestals. To switch off calibration of data
66// set the Calibration Mode to kSkip. To switch on pedestal calibration call either
67// SetPedestalFlag(MCalibrateData::kRun) (calibration is done once in ReInit)
68// SetPedestalFlag(MCalibrateData::kEvent) (calibration is done for each event)
69//
70// By calling AddPedestal() you can control the name of the
71// MPedestalCam and/or MPedPhotCam container which is used.
72//
73// Assume you want to calibrate "MPedestalCam" once and "MPedestalFromLoGain" [MPedestalCam]
74// event-by-event, so:
75// MCalibrateData cal1;
76// cal1.SetCalibrationMode(MCalibrateData::kSkip);
77// cal1.SetPedestalFlag(MCalibrateData::kRun);
78// MCalibrateData cal2;
79// cal2.SetCalibrationMode(MCalibrateData::kSkip);
80// cal2.AddPedestal("FromLoGain");
81// cal2.SetPedestalFlag(MCalibrateData::kEvent);
82//
83//
84// Input Containers:
85// [MPedestalCam]
86// [MExtractedSignalCam]
87// [MCalibrationChargeCam]
88// [MCalibrationQECam]
89// MBadPixelsCam
90//
91// Output Containers:
92// [MPedPhotCam]
93// [MSignalCam]
94//
