Detailed Description

Author: to be filled - doc by L.Martin

Date: 02/27/04 for the documentation

This class is the description of the SSD wafer objects. A wafer is made of :

An unique Id
Some geometrical information such as the transverse,drift and normal vectors, the position of its center
Two lists of strips
Two lists of clusters
A list of packages (matchable clusters)
A list of points deduced from the packages

The Clusters are first found on both sides of the wafer. The clusters are then combined into packages. The packages are then solved and the points deduced from the packages. The point coordinates can be transformed from the UV frame to the local (wafer) frame and the global frame.

void StSsdWafer::addCluster	(	StSsdCluster *	ptr,
		Int_t	iSide
	)

Attaches the ptr cluster on the iSide of the wafer.

A new cluster is added to the wafer by calling the ClusterList method.

Definition at line 212 of file StSsdWafer.cc.

void StSsdWafer::addPackage ( StSsdPackage * ptr )

Attaches the ptr package on that wafer.

A new package is added to the wafer by calling the PackageList method.

Definition at line 223 of file StSsdWafer.cc.

void StSsdWafer::addPoint ( StSsdPoint * ptr )

Attaches the ptr point on that wafer.

A new point is added to the wafer by calling the PointList method.

Definition at line 229 of file StSsdWafer.cc.

void StSsdWafer::addStrip	(	StSsdStrip *	ptr,
		Int_t	iSide
	)

Attaches the ptr strip on the iSide of the wafer

A new strip is added to the wafer by calling the StripList method.

Definition at line 201 of file StSsdWafer.cc.

void StSsdWafer::doClusterisation	(	Int_t *	NClusterPerSide,
		StSsdClusterControl *	clusterControl
	)

Does the cluster finding in two steps for both sides :

a cluster finding
a cluster splitting

Definition at line 270 of file StSsdWafer.cc.

References doClusterSplitting(), and doFindCluster().

Int_t StSsdWafer::doClusterSplitting	(	StSsdClusterControl *	clusterControl,
		Int_t	iSide
	)

Does the cluster splitting on the side iSide. For each cluster in the cluster list, the array of signal values is built and transmitted to the splitCluster method. This method seems to remove clusters and not to add new clusters resulting from a cluster splitting into several.

Int_t StSsdWafer::doFindCluster	(	StSsdClusterControl *	clusterControl,
		Int_t	iSide
	)

Does the cluster finding.

Does the cluster finding on the iSide. The strip list is scanned by increasing order (the list is assumed to be sorted). For a given strip (CurrentStrip) if its signal is above a given number of time its noise value a cluster list is formed. The strip list is scanned backward then forward to add the consecutive strips with a signal. The new cluster is updated each time a new strip is added. The scan starts with the first strip of the list and ends with the last strip. The threshold for the creation of a new cluster is given by SsdClusterControl.highCut. The SsdClusterControl table seems to be useless in this method (cleaning needed ?)

Int_t StSsdWafer::doFindPackage	(	ssdDimensions_st *	dimensions,
		StSsdClusterControl *	clusterControl
	)

Determines the packages by comparing the cluster lists built for both sides. Still a mystery for me...

Definition at line 492 of file StSsdWafer.cc.

References geoMatched().

void StSsdWafer::doLorentzShift	(	ssdDimensions_st *	dimensions,
		Float_t	mShift_hole,
		Float_t	mShift_elec
	)

Does the loretnz shift of the mean strip of the cluster Up->Up+2.47um Un->Un+12,45 um

Definition at line 446 of file StSsdWafer.cc.

Int_t StSsdWafer::geoMatched	(	ssdDimensions_st *	dimensions,
		StSsdCluster *	ptr1,
		StSsdCluster *	ptr2
	)

Determines if two clusters are geometricaly compatible.

Determines if two clusters can be matched based on geometrical considerations

		Double_t *	rD,
		Double_t *	rT,
		Double_t *	rN,
		Double_t *	rX
	)

The wafer initialisation. The geom info is taken from the method arguments. The lists are built. Only the WafersPosition are used at the moment. This part should be updated to take into account the relative position of the ladders, sectors and barrel.

Must be useful but for what ???

Definition at line 2689 of file StSsdWafer.cc.

void StSsdWafer::sortCluster ( )

The clusters of both sides are sorted

Definition at line 252 of file StSsdWafer.cc.
