30// pedphotcalc.C
31//
32// This macro is an example of the use of MPedPhotCalc. It computes
33// the pedestal mean and rms from pedestal files undergoing the
34// signal extraction + calibration chain, in units of photons. It
35// produces plots of the relevant computed quantities.
36//
37// Needs as arguments the run number of a pedestal file ("*_P_*.root"),
38// one of a calibration file ("*_C_*.root").
39// performs the pedestal calculation, the calibration
40/// constants calculation and the calibration of the pedestals.
41//
42// The TString inpath has to be set correctly.
43//
44// The macro searches for the pulser colour which corresponds to the calibration
45// run number. If the run number is smaller than 20000, pulser colour "CT1"
46// is assumed, otherwise, it searches for the strings "green", "blue", "uv" or
47// "ct1" in the filenames. If no colour or multiple colours are found, the
48// execution is aborted.
