THaDecData : trigger pattern

The trigger pattern word D.evtypbits uses the trigger latch TDC data to generate this data. A window has to be defined to have a hit counted as a trigger. //_____________________________________________________________________________ void THaDecData::TrigBits(UInt_t ibit, BdataLoc *dataloc) { // Figure out which triggers got a hit. These are multihit TDCs, so we // need to sort out which hit we want to take by applying cuts. if( ibit >= kBitsPerByte*sizeof(UInt_t) ) return; //Limit of evtypebits bits.ResetBitNumber(ibit); static const UInt_t cutlo = 400; static const UInt_t cuthi = 1200; for (int ihit = 0; ihit < dataloc->NumHits(); ihit++) { if (dataloc->Get(ihit) > cutlo && dataloc->Get(ihit) < cuthi) { bits.SetBitNumber(ibit); evtypebits |= BIT(ibit); } } } //_____________________________________________________________________________
