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. //
|

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 | // HCharge(npix) (distribution of summed FADC time slice entries)
|
---|
56 | // HTime(npix) (distribution of position of maximum)
|
---|
57 | // HChargevsN(npix) (distribution of charges vs. event number.
|
---|
58 | //
|
---|
59 | // PostProcess: All histograms HCharge(npix) are fitted to a Gaussian
|
---|
60 | // All histograms HTime(npix) are fitted to a Gaussian
|
---|
61 | // The histogram HBlindPixelCharge (blind pixel) is fitted to a single
|
---|
62 | // PhE fit
|
---|
63 | // The histogram HBlindPixelTime (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:
