//   MCalibrateData
//
//   This task takes the integrated charge from MExtractedSignal and applies
//   the calibration constants from MCalibrationCam to convert the summed FADC 
//   slices into photons. The number of photons obtained is stored in MCerPhotEvt. 
//   Optionally, the calibration of pedestals from an MPedestalCam container into 
//   an MPedPhotCam container can be chosen with the member functions 
//   SetPedestalType(). Default is 'kRun', i.e. calibration of pedestals from a 
//   dedicated pedestal run.
//   In case, the chosen pedestal type is kRun or kEvent, in ReInit() the MPedPhotCam 
//   container is filled using the information from MPedestalCam, MExtractedSignalCam, 
//   MCalibrationChargeCam and MCalibrationQECam
//
//   Selection of different calibration methods is allowed through the 
//   SetCalibrationMode() member function (default: kFfactor)
//
//   The calibration modes which exclude non-valid pixels are the following: 
//
//     kFfactor:    calibrates using the F-Factor method
//     kBlindpixel: calibrates using the BlindPixel method
//     kBlindpixel: calibrates using the BlindPixel method
//     kFlatCharge: perform a charge flat-flatfielding. Outer pixels are area-corrected.
//     kDummy:      calibrates with fixed conversion factors of 1 and errors of 0.
//
//   The calibration modes which include all pixels regardless of their validity is:
//
//     kNone:       calibrates with fixed conversion factors of 1 and errors of 0.
//
//   Use the kDummy and kNone methods ONLY FOR DEBUGGING!
//
//
//   This class can calibrate data and/or pedestals. To switch off calibration of data
//   set the Calibration Mode to kSkip. To switch on pedestal calibration call either
//     SetPedestalFlag(MCalibrateData::kRun)    (calibration is done once in ReInit)
//     SetPedestalFlag(MCalibrateData::kEvent)  (calibration is done for each event)
//
//   By calling AddPedestal() you can control the name of the
//   MPedestalCam and/or MPedPhotCam container which is used.
//
//   Assume you want to calibrate "MPedestalCam" once and "MPedestalFromLoGain" [MPedestalCam]
//   event-by-event, so:
//     MCalibrateData cal1;
//     cal1.SetCalibrationMode(MCalibrateData::kSkip);
//     cal1.SetPedestalFlag(MCalibrateData::kRun);
//     MCalibrateData cal2;
//     cal2.SetCalibrationMode(MCalibrateData::kSkip);
//     cal2.AddPedestal("FromLoGain");
//     cal2.SetPedestalFlag(MCalibrateData::kEvent);
//
//
//   Input Containers:
//    [MPedestalCam]
//    [MExtractedSignalCam]
//    [MCalibrationChargeCam]
//    [MCalibrationQECam]
//    MBadPixelsCam
//
//   Output Containers:
//    [MPedPhotCam]
//    [MCerPhotEvt]
//
