where Tcommon is a fixed offset defined in
DTDigiSyncTOFCorr:offset (in ORCA the default was = 500 ns)
and aTOF is set according to MuBarDigiSyncTOFCorr:TOFCorrection:
0: no TOF correction (aTOF=0)
1: aTOF = the TOF of an infinite-momentum particle travelling from the nominal IP to the 3D center of the chamber
2: ditto, but for a particle travelling to the 3D center of the wire. (This mode is avaliable for comparison with older data which were produced in this way)
