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 MSignalCam.
|
---|
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

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.
