Int_t AliTrackletAODMCTask::CommonParent	(	Int_t	label,

protected

Find the the common parent of label and those given in fill, if any. If a common parent is found, return the index into fill of that parent.

Parameters

label	Particles who's parents we're checking
fill	List of known parents

Returns: Index of common parent of label and those in fill

TTree * AliTrackletAODMCTask::FilterClusters ( TTree * t )

protectedvirtual

Pre-process clusters. This can remove clusters, etc.

Parameters

t	Tree of clusters

Reimplemented from AliTrackletAODTask.

void AliTrackletAODMCTask::FilterClustersRandom	(	TTree *	t,
		TTree *	copy,
		Double_t	cent,
		Double_t	ipz
	)

protectedvirtual

Pre-process clusters. This can remove clusters independently of each other. That is, for each cluster we look up the parent primary particle(s), and find the corresponding weight \( w\). We then throw a dice and if number is larger than \( 1-1/w\), we remove the cluster.

Parameters

t	Tree of clusters
copy	Tree to fill with clusters
cent	Centrality (mostly 0)
ipz	Collision point z-coordinate

void AliTrackletAODMCTask::FilterClustersTrack	(	TTree *	t,
		TTree *	copy,
		Double_t	cent,
		Double_t	ipz
	)

protectedvirtual

Pre-process clusters. For all primary particles in the stack, we compute a weight \( w\). We then throw a dice, and if the number is larger than \( 1-1/w\), we mark that particle for removal. We then loop over all clusters in the SPD, and find the primary particle(s) that each cluster corresponds to. If such a primary particle is marked for removal, we remove the clusters.

Parameters

t	Tree of clusters
copy	Tree to fill with clusters
cent	Centrality (mostly 0)
ipz	Collision point z-coordinate

Int_t AliTrackletAODMCTask::FindParent ( Int_t label ) const

protected

Find parent of particle with label label. If no parent is found, or it goes beyond the stack, a negative value is returned.

Parameters

label Label particle to get the parent for

Returns: Label of parent to particle with label label.

Int_t AliTrackletAODMCTask::FindParents	(	Int_t	label,
		TArrayI &	fill,
		Int_t	offset
	)		const

protected

Find list of parents corresponding to passed label.

We find the labels of all parent particles and store into cache fill. Elements are assigned starting from offset. In this way, we can invoke this member function multiple times and fill into the same cache array.

Parameters

label	Starting particle
fill	Cache to fill into
offset	Offset in fill to start assigning into

Returns: Number of assigned elements
