/**

 *
 * Program to perform detector calibration using reconstructed muon trajectories.
 *
 * It is recommended 
 * to perform the detector calibration after JMuonGandalf.cc and 
 * to accordingly set option <tt>JMuonGandalfParameters_t::numberOfPrefits = 1</tt>, 
 * so that the best track from the previous output is used. 
 * Several histograms will be produced which can subsequently be processed with JHobbit.cc for 
 * the determination of the time calibration of optical modules and JFrodo.cc for the time-slewing correction.
