// $Log: BrTofTdcGainCalModule.h,v $
// Revision 1.4  2001/10/02 01:53:28  ouerdane
// Added SetSaveAscii, SetLoadAscii, SetCommitAscii and updated the way parameters are tagged for Use
//
// Revision 1.3  2001/07/31 09:22:15  ouerdane
// Removed all references to a TList member, replaced
// by histogram members, declare ntuple if fNtuple is true (set
// via SetNtuple)
//
// Revision 1.2  2001/07/18 16:14:42  ouerdane
// Updated this module:
//  - in Event:  fill histograms only when tdc (top or bot) is > 1 and < 4095
//  - added methods SetMinGain and SetMaxGain (with corresponding private members)
//    to set some reasonable limits to what the gains should be)
//    if the calculated gain is beyond this range, the
//    BrTofCalibration::kCalException is assigned. The range by default is
//    [0.023, 0.027] ns.
//  - added SetTimeStep and fTimeStep so that the user can set the time step of
//    the pulser (10 ns by default)
//  - made it compatible with brat2 and tested it (script available in
//    brahms_app/do_app/tof/mm_scripts/tofTdcGain.C and commitTdcGain.C)
//
// Revision 1.1.1.1  2001/06/21 14:55:06  hagel
// Initial revision of brat2
//
// Revision 1.1  2001/06/19 12:44:58  ouerdane
// Added calibration classes and reconstruction classes.
// Brat compiles but these classes haven't been tested in this
// context. Be careful if you use them before I (DO) check if
// all is ok.
