Detailed Description

converts TrackerHits of a TimePix into further separated TrackerHits, by projecting them onto their own clusteraxis.

This projection is weighted by charge information if available, that is if the pixel was operated in TOT mode.
Conditionsdata must be stored in a seperate collection of TimePixPixelMode for every event in which the mode of operation changes.
Handling of conditions data is done by the ConditionsProcessor

Input - Prerequisites

a collection of TrackerHits containing clusters of adjacent pixels

Output

• Collection containing TrackerHits of further separated clusters, separation by projection along cluster axis.
• Collection of tracker data objects which has been split because it belonged to several clusters

Parameters

InputCollectionName	Name of the input collection with unseparated hit candidates (default "TimePixHitCandidates")
OutputCollectionName	Name of the output containing with sepatated hit candidates (default "TimePixSepHitCandidates")
OutputTrackerDataCollectionName	Name of the output collection with sepatated tracker data objects (default "TimePixSepData")
OutputRelationsCollectionName	Name of the collection with relations between clusters and tracker data (default "TimePixRelationSepHit")
nColumn	number of columns on the chip
nRow	number of rows on the chip
clusterSizeToSep	number of pixels in a cluster for it to be separated (default 9)
SetOutputTransient	If not 0 the output collection is set transient
