| 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. //

|

|
|---|
| 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. //
|
|---|

|

|

|
|---|
| 56 | // HT(npix) (distribution of position of maximum) //
|
|---|
| 57 | // HQvsN(npix) (distribution of charges vs. event number. //
|
|---|
| 58 | // //
|
|---|
| 59 | // PostProcess: All histograms HQ(npix) are fitted to a Gaussian //
|
|---|
| 60 | // All histograms HT(npix) are fitted to a Gaussian //
|

| 61 | // The histogram HBPQ (blind pixel) is fitted to a single //
|
|---|
| 62 | // PhE fit //
|
|---|
| 63 | // The histogram HBPT (blind pixel) is fitted to a Gaussian //
|
|---|
| 64 | // The histograms of the PIN Diode are fitted to Gaussians //
|
