Detailed Description

Processor to analyse Criteria of true tracks.

Criteria are classes derived from ICriterion in KiTrack. They are used by the Cellular Automaton to determine what tracksegments might belong together. (For more information on Criteria and the Cellular Automaton see the KiTrack package.)

This processor analyses the values of these criteria, that true tracks produce. The results are stored in the trees of a root file. Additional to information about the criteria, fit information and the distances of hits in a track are stored.

It is intended as a tool to finde appropriate values for the steering of the Cellular Automaton.

Input - Prerequisites

The true tracks to be analysed

Output

A root file containing information on the criteria

Parameters

MCTrueTrackRelCollectionName	Name of the TrueTrack MC Relation collection (default value TruthTracksMCP )
RootFileName	Name of the root file for saving the results (default value TrueTracksCritAnalysis.root )
WriteNewRootFile	What to do with older root file: true = rename it, false = leave it and append new one (default value true )
CutChi2Prob	Tracks with a chi2 probability below this value won't be considered (default value 0.005 )
CutPtMin	The minimum transversal momentum pt above which tracks are of interest in GeV (default value 0.1 )
CutDistToIPMax	The maximum distance from the origin of the MCP to the IP (0,0,0) (default value 100 )
CutNumberOfHitsMin	The minimum number of hits a track must have (default value 4 )
OverlappingHitsDistMax	The maximum distance of hits from overlapping petals belonging to one track (default value 4 )
MultipleScatteringOn	Whether to take multiple scattering into account when fitting the tracks (default value true )
EnergyLossOn	Whether to take energyloss into account when fitting the tracks (default value true )
SmoothOn	Whether to smooth all measurement sites in fit (default value false )
