Member Function Documentation

◆ add()

bool add	(	VxdID	nextID,
		int	nextCharge,
		unsigned short	nextCellID,
		float	nextStripSNR,
		unsigned short	maxClusterSize
	)

inline

add a new strip to the current cluster candidate if possible

Parameters

nextID	VxdID of the digit to be added
nextCharge	charge (in ADU) of the digit to be added
nextCellID	strip number of the digit to be added
nextStripSNR	SNR of the digit to be added
maxClusterSize	maximum cluster size, if exceeded, start new cluster

Returns: true if digit was successfully added to current cluster candidate, else return false

      bool added = false;
 
      // do not add if you are on the wrong sensor or side
      if (vxdID != nextID) return false;
 
      // add if it's the first strip
      if (strips.size() == 0) added = true;
 
      // add if it adjacent to the last strip added (we assume that SVDRecoDigits are ordered)
      // and if cluster size would still be <= 4 strips
      if (strips.size() > 0 and nextCellID == strips.back() + 1 and strips.size() < maxClusterSize) {
        added  = true;
      }
 
      //add it to the vector od strips, update the seed nextCharge and index:
      if (added) {
        strips.push_back(nextCellID);
        charges.push_back(nextCharge);
 
        if (nextCharge > seedCharge) seedCharge = nextCharge;
 
        if (nextStripSNR > maxSNRinClusterCandidate) {
          maxSNRinClusterCandidate = nextStripSNR;
        }
      }
      return added;
 
    };

◆ finalizeCluster()

void finalizeCluster	(	const double	pitch,
		const int	stripsInSensor
	)

inline

calculate cluster properties once a cluster is ready to be stored

Parameters

pitch	strip pitch of the sensor and sensor side on which the cluster was found
stripsInSensor	number of strips of the sensor and sensor side on which the cluster was found
