//  calibration.C
//
//  Needs as arguments the run number of a calibration file ("*_C_*.root") and 
//  the run number of the corresponding pedestal file ("*_P_*.root"). 
//
//  The TString inpath has to be set correctly.
//
//  The macro searches for the pulser colour which corresponds to the calibration
//  run number. If the run number is smaller than 20000, pulser colour "CT1" 
//  is assumed, otherwise, it searches for the strings "green", "blue", "uv" or 
//  "ct1" in the filenames. If no colour or multiple colours are found, the 
//  execution is aborted.  
//
//  The container MBadPixelsCam is created and followed during the execution of the 
//  rest of the macro.
// 
//  A first loop over the pedestal file is performed using the class MJPedestal
//
//  The container MCalibrationQECam is created and followed during the execution of the 
//  rest of the macro.
//
//  A loop over the calibration files is performed using the class MJCalibration. 
//  The results are displayed using the MJCalibration::SetNormalDisplay() facility, 
//  but other displays can easily be uncommented. 
//  The call to MJCalibration skips the relative time calibration, which can be 
//  uncommented as well.
