731afc39 18Revision 1.20.1 2007/05/19 decaro
19 Added the following methods:
20 GetVolumeIndices(Int_t index, Int_t *det), to get
21 the volume indices (sector, plate, strip, padz, padx,
22 stored respectively in det[0], det[1], det[2], det[3], det[4])
23 from the calibration channel index;
24 NStrip(Int_t nPlate), to get the strips number
25 per each kind of TOF module.
