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: 63.5 +- 0.1 mm^2
38// Transparency of window T: 0.88 +- 0.05
39//
40// Ratio of areas:
41//
42// Distance of PIN Diode to pulser D1: 1.139 +- 0.005 m
43// Distance of Inner Pixel to pulser D2: 18.135 +- 0.015 m
44//
45// D1*D1
46// gkSolidAngleRatio = -------- = 7.06 * 10^-5
47// Ap*T*D2*D2
48//
49// gkSolidAngleRatioErr = 0.4 * 10^-5
