Member Function Documentation

calculate()

void CaloClusterCorr::SamplingHelper_Cluster::calculate ( double eta, double phi, double deta, double dphi, CaloSampling::CaloSample sampling, bool dofill = false )

virtual

Calculate layer variables.

Parameters

eta	Center of the cluster in \(\eta\).
phi	Center of the cluster in \(\phi\).
deta	Full width of the cluster in \(\eta\).
dphi	Full width of the cluster in \(\phi\).
sampling	The sampling for which to do the calculation.
dofill	(Ignored for this implementation.)

This method selects the cells within the specified window in the specified sampling from the list of candidate cells and calculates the layer variables.

The result of the calculation will be held in internal variables.

Implements CaloClusterCorr::SamplingHelper.

Definition at line 742 of file CaloFillRectangularCluster.cxx.

{
  calculate_cluster (eta, phi, deta, dphi, sampling);
}

calculate_and_set()

void CaloClusterCorr::SamplingHelper::calculate_and_set ( double eta, double phi, int layer, int fallback_layer, const CaloSampling::CaloSample samplings[4], bool allow_badpos = false )

inherited

Calculate layer variables and update cluster.

Parameters

eta	Center of the cluster in \(\eta\).
phi	Center of the cluster in \(\phi\).
layer	Calorimeter layer being calculated (0-3).
fallback_layer	Layer for fallback values (see below).
samplings	List of samplings for this region.
allow_badpos	Should error flags be allowed into the cluster?

This method selects the cells within the specified window for the sampling for the specified layer from the current list of cells in the cluster and calculates the layer variables.

The result of the calculation will be held in internal variables. In addition, the cluster variables for this sampling will be updated with the result.

In some cases, the calculation of the cluster position may yield an error (for example, if there are no selected cells). In this case, we use the cluster eta/phi from the layer given by fallback_layer instead of the calculated result. (If fallback_layer is < 0, then we use the eta, phi arguments instead.) If allow_badpos is true, then the error flags are used to update the cluster variables; otherwise, the fallback position is used when updating the cluster.
