32// MCalibrateData
33//
34// This task takes the integrated charge from MExtractedSignal and applies
35// the calibration constants from MCalibrationCam to convert the summed FADC
36// slices into photons. The number of photons obtained is stored in MCerPhotEvt.
37// Optionally, the calibration of pedestals from an MPedestalCam container into
38// an MPedPhotCam container can be chosen with the member functions
39// SetPedestalType(). Default is 'kRun', i.e. calibration of pedestals from a
40// dedicated pedestal run.
41// In case, the chosen pedestal type is kRun or kEvent, in ReInit() the MPedPhotCam
42// container is filled using the information from MPedestalCam, MExtractedSignalCam,
43// MCalibrationChargeCam and MCalibrationQECam
44//
45// Selection of different calibration methods is allowed through the
46// SetCalibrationMode() member function (default: kFfactor)
47//
48// The calibration modes which exclude non-valid pixels are the following:
49//
50// kFfactor: calibrates using the F-Factor method
51// kBlindpixel: calibrates using the BlindPixel method
52// kBlindpixel: calibrates using the BlindPixel method
53// kFlatCharge: perform a charge flat-flatfielding. Outer pixels are area-corrected.
54// kDummy: calibrates with fixed conversion factors of 1 and errors of 0.
55//
56// The calibration modes which include all pixels regardless of their validity is:
57//
58// kNone: calibrates with fixed conversion factors of 1 and errors of 0.
59//
60// Use the kDummy and kNone methods ONLY FOR DEBUGGING!
61//
62//
63// This class can calibrate data and/or pedestals. To switch off calibration of data
64// set the Calibration Mode to kSkip. To switch on pedestal calibration call either
65// SetPedestalFlag(MCalibrateData::kRun) (calibration is done once in ReInit)
66// SetPedestalFlag(MCalibrateData::kEvent) (calibration is done for each event)
67//
68// By calling SetNamePedADCContainer() and/or SetNamePedPhotContainer() you
69// can control the name of the MPedestalCam and/or MPedPhotCam container which is used.
70//
71// Assume you want to calibrate "MPedestalCam" once and "MPedestalFromLoGain" [MPedestalCam]
72// event-by-event, so:
73// MCalibrateData cal1;
74// cal1.SetCalibrationMode(MCalibrateData::kSkip);
75// cal1.SetPedestalFlag(MCalibrateData::kRun);
76// MCalibrateData cal2;
77// cal2.SetCalibrationMode(MCalibrateData::kSkip);
78// cal2.SetNamePedADCContainer("MPedestalFromLoGain");
79// cal2.SetNamePedPhotContainer("MPedPhotFromLoGain")
80// cal2.SetPedestalFlag(MCalibrateData::kEvent);
81//
82//
83// Input Containers:
84// [MPedestalCam]
85// [MExtractedSignalCam]
86// [MCalibrationChargeCam]
87// [MCalibrationQECam]
88// MBadPixelsCam
89//
90// Output Containers:
91// [MPedPhotCam]
92// [MCerPhotEvt]
