Member Function Documentation

AddBranchName() [1/2]

virtual void PndIdealTrackFinder::AddBranchName ( TString  name )

inlinevirtual

Add a branch name of detector hits which should be added to the PndTrack. If no branch name is given per default all hits of tracking detectors are taken.

Parameters

name	name of branch in input root file

Definition at line 37 of file PndIdealTrackFinder.h.

References fBranchNames.

  {
    fBranchNames.push_back(name);
  }

AddBranchName() [2/2]

virtual void PndIdealTrackFinder::AddBranchName ( TString  name, TString  mcName  )

inlinevirtual

Add a branch name of detector hits which should be added to the PndTrack. If no branch name is given per default all hits of tracking detectors are taken.

Parameters

name	name of branch in input root file
mcName	name of the branch which contains the MC points connected to the hit branch. If no mcName is given a default map is taken.

SetMomentumSmearing()

void PndIdealTrackFinder::SetMomentumSmearing ( Double_t  sigmax, Double_t  sigmay, Double_t  sigmaz  )

inline

Sets how much the mc truth momentum values are smeared by absolute values

Parameters

sigmax	absolute smearing in px in [GeV/c]
sigmay	absolute smearing in py in [GeV/c]
sigmaz	absoulte smearing in pz in [GeV/c]

SetOutputBranchName()

virtual void PndIdealTrackFinder::SetOutputBranchName ( TString  name )

inlinevirtual

Sets the output branch name of the generated PndTracks. If this method is not called "IdealTrack" is taken.

Parameters

name	name of branch in output root file

SetPersistence()

void PndIdealTrackFinder::SetPersistence ( Bool_t  persistence )

inline

Defines if the output track candidates are stored to a file or are just transient.

SetRelativeMomentumSmearing()

void PndIdealTrackFinder::SetRelativeMomentumSmearing ( Double_t  dpop )

inline

Sets how much the mc truth momentum values are smeared by a relative value. The relative smearing is applied to pt and pz individually. => The error applied to px and py is 1/Sqrt(2) * dpop while for pz it is dpop

Parameters

dpop	relative momentum smearing

References fRunTimeBased.

{ fRunTimeBased = valRunTimeBased; };

SetTrackingEfficiency()

void PndIdealTrackFinder::SetTrackingEfficiency ( Double_t  eff = 1. )

inline

Sets an artificial efficiency of the ideal track finder

Parameters

eff	Fraction of tracks which are generated. A value of 1 means all ideal tracks, 0 no tracks are generated.

Definition at line 110 of file PndIdealTrackFinder.h.

References fEfficiency.

{ fEfficiency = eff; };

SetTrackSelector()

void PndIdealTrackFinder::SetTrackSelector ( TString  selector )

inline

The track selector decides which kind of ideal tracks are generated from the features of MC tracks. E.g. the "StandardTrackFunctor" creates a track if more than 3 MVD hits or more than 5 (MVD+STT+GEM) hits are from the same track.

Parameters

selector

string which defines a track selector. Valid strings can be found in PndTrackFunctor

Parameters

sigmax	absolute smearing in x in [cm]
sigmay	absolute smearing in y in [cm]
sigmaz	absoulte smearing in z in [cm]
