// Revision 1.3  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 1.2  2001/11/05 06:56:32  ouerdane
// added the possibility to use the slewing correction in the delta tdc calculation
//
// Revision 1.1  2001/10/16 02:08:49  ouerdane
// Added the delta tdc calibration. Needed for slewing correction
// since we want to select within 2 sigma dt (remove outlier hits
// that distort the slewing profile).
