27// MCalibrationChargePINDiode
28//
29// Storage container of the fit results of the PIN Diode signal
30// (from MHCalibrationChargePINDiode). The PIN Diode is not yet working, so
31// is the documentation for the moment.
32//
33// The Flux is calculated in photons per mm^2 in the camera plane.
34//
35// Currently, the following numbers are implemented:
36//
37// Area of PIN Diode Ap: 100.000 +- 10 mm^2
38//
39// Ratio of areas:
40//
41// Distance of PIN Diode to pulser D1: 1.5 +- 0.3 m
42// Distance of Inner Pixel to pulser D2: 18.0 +- 0.5 m
43//
44// D1*D1
45// gkSolidAngleRatio = -------- = 0.00007
46// Ap*D2*D2
47//
48// gkSolidAngleRatioErr = 0.00002
