Constructor & Destructor Documentation

FMSCluster::StFmsClusterFinder::StFmsClusterFinder

(

double

energyCutoff = 0.5

)

Constructor.

The argument sets the energy cutoff on towers - towers below this are not included in the calculation of the cluster moments (mean and sigma x, y).

Member Function Documentation

void FMSCluster::StFmsClusterFinder::calculateClusterMoments

(

StFmsTowerCluster *

cluster

)

const

Calculate moments (mean and sigma of tower (x, y) positions) for a cluster.

Also update the cluster with the current number of towers in it.

int FMSCluster::StFmsClusterFinder::categorise

(

StFmsTowerCluster *

cluster

)

Categorise a cluster based on its energy and tower distribution.

Set the cluster's category field and return that category. See StFmsClusterCategory in StEvent/StFmsCluster.h for valid categories.

int FMSCluster::StFmsClusterFinder::findClusters	(	TowerList *	towers,
		ClusterList *	clusters,
		int	detetorId
	)

Find clusters from a collection of input towers.

Populate the cluster list with the found clusters. Arguments:

• towers: input tower list. Note it may be modified (elements erased or reordered) so do not rely on its contents after calling findClusters().
• clusters: output cluster list. Newly found clusters are appended to the list.

Return the number of found clusters.

Todo:

Check that this sort action is still needed
