// $Log: BrTpcCalibration.h,v $
// Revision 1.5  2002/08/15 16:15:52  videbaek
// Commit changes made to be able to apply adcgain correction
// as well as 'timing' offsets. This still has to be worked completely
// out how to calibrate and how to use.
//
// Revision 1.4  2001/11/28 15:18:28  pchristi
// Changed padstatus to short and removed hitwidths.
//
// Revision 1.3  2001/11/15 13:40:17  pchristi
// Modified Get*Data to return pointers instead of references because of unexpected error
// that I did not understand.
//
// Revision 1.2  2001/11/15 12:46:46  pchristi
// Added methods to get the BrCalibrationData and thereby the run no for the calibration.
//
// Revision 1.1  2001/10/12 11:00:47  pchristi
// Added a BrTpcCalibration base class for the TPC calibrations.
//
//
