Constructor & Destructor Documentation

StFmsEventClusterer::StFmsEventClusterer	(	const StFmsGeometry *	geometry,
		Int_t	detectorId
	)

Constructor.

Clustering is done per sub-detector, so initialize with the detector ID and FMS geometry information.

See FMSCluster::StFmsDetectorId for valid detector IDs.

Definition at line 108 of file StFmsEventClusterer.cxx.

StFmsEventClusterer::~StFmsEventClusterer ( )

Destructor.

Definition at line 114 of file StFmsEventClusterer.cxx.

FMSCluster::StFmsEventClusterer::StFmsEventClusterer ( const StFmsEventClusterer & )

private

Disallow copy construction.

With the various collections of towers, clusters and photons, many of which are dynamically allocated, it becomes too complicated to easily implement copying, and there is little reason to need it. Therefore prevent it from happening.

Member Function Documentation

Bool_t StFmsEventClusterer::cluster ( std::vector< FMSCluster::StFmsTower > * towers )

Perform cluster-finding and photon-fitting on a list of towers.

Returns true if photon fits to all clusters succeed, or false if one or more clusters have a photon fit with a chi-square exceeding the maximum allowed value.

Todo:: Test of number of towers should be detector-dependent

Definition at line 120 of file StFmsEventClusterer.cxx.

Here is the call graph for this function:

Here is the caller graph for this function:

ClusterList& FMSCluster::StFmsEventClusterer::clusters ( )

inline

Returns the list of clusters in this detector for the event.

Definition at line 55 of file StFmsEventClusterer.h.

Here is the caller graph for this function:

const ClusterList& FMSCluster::StFmsEventClusterer::clusters ( ) const

inline

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Definition at line 57 of file StFmsEventClusterer.h.

int FMSCluster::StFmsEventClusterer::detector ( ) const

inline

Returns the ID of the detector for which clustering is being performed.

See FMSCluster::StFmsDetectorId for valid detector IDs.

Definition at line 44 of file StFmsEventClusterer.h.

Float_t StFmsEventClusterer::fit2PhotonClust ( ClusterIter cluster )

private

Definition at line 387 of file StFmsEventClusterer.cxx.

Int_t StFmsEventClusterer::fitEvent ( )

private

Perform all clustering and photon-fitting for the current event.

Returns the final status for the event: true for "all good", false for "something was bad".

Todo:: Change return type to bool.

Definition at line 133 of file StFmsEventClusterer.cxx.

Float_t StFmsEventClusterer::fitOnePhoton ( StFmsTowerCluster * cluster )

private

Perform a 1-photon fit on a single cluster.

Returns the χ² of the fit.

Definition at line 271 of file StFmsEventClusterer.cxx.

Here is the call graph for this function:

Float_t StFmsEventClusterer::globalFit	(	const Int_t	nPh,
		const Int_t	nCl,
		ClusterIter	first
	)

private

Todo:: Improve this implementation? This approach is necessary because the original code uses a pointer to a StFmsTowerCluster in the fitting routines as both a pointer to a single cluster, and an array of clusters .

Definition at line 306 of file StFmsEventClusterer.cxx.

StFmsEventClusterer& FMSCluster::StFmsEventClusterer::operator= ( const StFmsEventClusterer & )

private

Disallow assignment.

Double_t StFmsEventClusterer::photonEnergyInCluster	(	Double_t	towerWidth,
		const StFmsTowerCluster *	cluster,
		const StFmsFittedPhoton *	photon
	)		const

private

The energy deposit in a cluster by a photon.

This is the sum over all towers making the cluster.

Definition at line 245 of file StFmsEventClusterer.cxx.

Here is the call graph for this function:

Double_t StFmsEventClusterer::photonEnergyInTower	(	Double_t	towerWidth,
		const StFmsTower *	tower,
		const StFmsFittedPhoton *	photon
	)		const

private

The energy deposit in a tower by a photon.

Calculated using the shower-shape function.

Definition at line 258 of file StFmsEventClusterer.cxx.

Here is the call graph for this function:

bool StFmsEventClusterer::validate2ndPhoton ( ClusterConstIter cluster ) const
