// $Log: BrBbCalModule.h,v $
// Revision 1.5  2002/03/21 15:02:17  ouerdane
// added fComment member to base class module and method SetComment so that the user can set comments about the calibration at commit time
//
// Revision 1.4  2002/03/20 19:30:52  videbaek
// Add the INL and INR counters to be dealt with for calibration and timing
// In the 2002 pp run there were not really of BB kind since they only have
// td information, but it is most convinientn to deal with them as BB calibration
// data.
//
// Revision 1.3  2001/10/15 00:35:08  ouerdane
// Updated all Beam-Beam counter calibration modules (like I did for the TOF
// some weeks ago):
//
// Common changes:
//  added methods Set[Save,Commit,Load]Ascii(Bool_t)
//  removed methods Set[ReadFrom,LoadFrom,SaveTo]File
//
// BrBbGainCalModule:
//  cleaned up a lot the code, added diagnostic histograms showing calibrated
//  ADC after the 1st MIP peak was found.
//  Still at a stage where the 1st MIP peak is the only one to be checked.
//  Later on, will add algorithm to find other peaks.
//
// Added BrBbSlewingCalModule in Makefile.am, etc
// The fit function introduced is dT = a + b/sqrt(dE) + c/dE (where dE = ADC/Gain0)
//
// Revision 1.2  2001/09/23 01:51:51  videbaek
// Added prototype Gain calibration module. Updated others to deal with
// Load from File. This may be temporary, but does not break any code as far as
// I can tell.
//
// Revision 1.1  2001/07/23 11:39:56  ouerdane
// Added calibration modules for Beam-Beam counters
//  BrBbCalModule:       base class
//  BrBbPedCalModule:    pedestals
//  BrBbTdcGaincalModule tdc gains
//
// Updated Makefile.am, LinkDef.h, Include.h
//
