Detailed Description

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 JMuonGandalfParameters_t::numberOfPrefits = 1, 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.
