Cardinality (Maximum number of clones that can exist) special value 0 means that algorithm is reentrant.

Override this to return 0 for reentrant algorithms.

ClusterShapeMethod()

void BeamBackgroundFiller::ClusterShapeMethod ( Cache &  cache ) const

private

This function is the implementation of the "Cluster-Shape Method".

The shape of the cluster is described by the variable dr/dz which is the ratio of the standard deviation of the radial position of the contianed cells and the standard deviation of the z-position of the contained cells. Only the clusters matched with muon segments are checked.

OneSidedMethod()

void BeamBackgroundFiller::OneSidedMethod ( Cache &  cache ) const

private

This function is the implementation of the "No-Time Method" and the "One-Sided Method".

The "One-Sided Method" compares the time of the calorimeter cluster with the expected time. The expected time is calculated based on the direction of the beam background muon which is reconstructed from the position and time of the muon segment. The "No-Time Method" does not use the time information of the muon segment thus the direction of the beam background muon is not known. Therefore, the cluster time is compared to two expected time values (corresponding to both A->C and C->A directions).
