// $Log: BrTpcTimeCalModule.h,v $
// Revision 1.2  2001/11/02 13:38:54  pchristi
// Added new module for calibrating drift velocities using the fibres behind
// T2 and in front of T1.
// Updated old modules with small changes.
//
// Revision 1.1  2001/10/12 11:08:51  pchristi
// Added new directory tpc. Added the first calibration modules. They
// have all been tested and found to work. The algorithms might not be
// optimal, but are at least fully automatic and to some extent
// documented.  CVS:

// Revision 1.3  2001/10/10 15:49:55  pchristi
// Many updates and a new module
//
// Revision 1.2  2001/10/08 10:30:29  pchristi
// Classes compiles now

// Revision 1.1  2001/10/08 08:08:22  pchristi
// Initial revision.
//
// Revision 1.3  2001/10/02 01:53:28  ouerdane
// Added SetSaveAscii, SetLoadAscii, SetCommitAscii and updated the way parameters are tagged for Use
//
// Revision 1.2  2001/07/31 09:22:27  ouerdane
// Removed all references to a TList member, replaced
// by histogram members, declare ntuple if fNtuple is true (set
// via SetNtuple)
//
// Revision 1.1  2001/06/29 13:52:43  cholm
// Imported TOF classes from Djamel
