Detailed Description

calculates the center of gravity of each cluster, weighted by charge information.

Input - Prerequisites

a collection of TrackerHits, position not set

Output

Collection of TrackerHits with the position and dEdx set.

Parameters

InputCollectionName	Name of input collection, TrackerHits without position
OutputCollectionName	Name of output collection, TrackerHits with position
ModeMapCollectionName	Name of mode map collection
_max_zDiffusion_perCluster	pixels further than _max_zDiffusion_perCluster [clock cycles] away from the mean cluster time are ignored during cluster center calculation
SetOutputTransient	If not 0 the output collection is set transient
nColumn	number of columns on the chip
nRow	number of rows on the chip
pitch	pitch of the pixel
_minNrOfPixelsToCalcTime	if there are less than _minNrOfPixelsToCalcTime with 4 or more neighbors with charge all time pixels are taken into account for mean time calculation
_keepClusterHistoFlag	decide whether you want to keep a histo of z-Distribution for each Cluster - default is FALSE
rmsCut	pixels further away in z than rmsCut * RMSofDistributon are ignorred for Meancalculation
SetOutputTransient	If not 0 the output collection is set transient
