Detailed Description

A class for hits in a drift cell

Author

C. Grandi, S. Vanini Modifications: 28/X/02 S.Vanini: tshift=425 included in register 1/IV/03 SV time in clock units included: _clockTime –> operation with drift time are commented 22/VI/04 SV: last trigger code update 15/I/07 SV : new config update
