Detailed Description

Determination of cluster parameters.

Author

This class implements the determination of STS cluster parameters (time, position, charge) and their errors from the digis contained in the cluster.

The mathematics is described in: H. Malygina, Hit Reconstruction for the Silicon Tracking System of the CBM experiment, PhD thesis, Goethe-Universität Frankfurt, 2018

◆ WeightedMean()

Double_t CbmStsAlgoAnaCluster::WeightedMean ( CbmStsCluster cluster,
const CbmStsParModule modPar 
)
private

Weighted mean cluster position.

Parameters
clusterPointer to cluster object
modulePointer to module object
Returns
cluster position

This procedure is used when the result obtained by AnaSizeN are outside the range of the involved channels. This can happen e.g. for incomplete clusters, e.g. those cut at the edge of sensor.
