Member Function Documentation

createTruthTree()

virtual const TruthTree Muon::IMuonTrackTruthTool::createTruthTree ( const TrackRecordCollection * truthTrackCol, const McEventCollection * mcEventCollection, const std::vector< const MuonSimDataCollection * > & muonSimData, const CscSimDataCollection * cscSimDataMap ) const

pure virtual

create truth tree from sim data

getAncestor()

virtual HepMC::ConstGenParticlePtr Muon::IMuonTrackTruthTool::getAncestor ( const TruthTrajectory & traj, const int barcodeIn ) const

pure virtual

Returns the ancestor particle of the particle with barcodeIn if it is found in the truth trajectory.

Ancestor here means the last particle at generator level that has a status code different from final state, e.g. Z

getInitial()

virtual HepMC::ConstGenParticlePtr Muon::IMuonTrackTruthTool::getInitial ( const TruthTrajectory & traj, const int barcodeIn ) const

pure virtual

Returns the initial particle of the particle with barcodeIn if it is found in the truth trajectory.

For example a mu undergoing a mubrem would create a second mu, in which case this method returns the mu prior to bremsstrahlung.

getMother()

virtual HepMC::ConstGenParticlePtr Muon::IMuonTrackTruthTool::getMother ( const TruthTrajectory & traj, const int barcodeIn ) const

pure virtual

returns the mother particle of the particle with barcodeIn if it is found in the truth trajectory It traces the decay chain until if finds the first particle that is different flavor from the starting one.

getNumberOfScatters()

virtual unsigned int Muon::IMuonTrackTruthTool::getNumberOfScatters ( const TruthTrajectory & traj, const int barcodeIn ) const

pure virtual

Returns the number of steps a particle took while maintaining its PDG ID.

getTruth() [1/4]

virtual MuonTrackTruth Muon::IMuonTrackTruthTool::getTruth ( const TruthTree & truth_tree, const Muon::MuonSegment & segment ) const

pure virtual

get segment truth

getTruth() [2/4]

virtual MuonTrackTruth Muon::IMuonTrackTruthTool::getTruth ( const TruthTree & truth_tree, const std::vector< const MuonSegment * > & segments, bool restrictedTruth = false ) const

pure virtual

get segment truth for a list of segments, the segments will be considered to belong to the same muon

getTruth() [3/4]

virtual MuonTrackTruth Muon::IMuonTrackTruthTool::getTruth ( const TruthTree & truth_tree, const std::vector< const Trk::MeasurementBase * > & measurements, bool restrictedTruth = false ) const

pure virtual

get truth for a give set of hits.

If restrictedTruth is set to true only missed hits in chambers with hits will be counted.

getTruth() [4/4]

virtual MuonTrackTruth Muon::IMuonTrackTruthTool::getTruth ( const TruthTree & truth_tree, const Trk::Track & track, bool restrictedTruth = false ) const

pure virtual

get track truth

interfaceID()

match() [1/2]

virtual SegmentResultVec Muon::IMuonTrackTruthTool::match ( const TruthTree & truth_tree, const std::vector< const MuonSegment * > & segments ) const

pure virtual

perform truth matching for a given set of segments

match() [2/2]

virtual ResultVec Muon::IMuonTrackTruthTool::match ( const TruthTree & truth_tree, const TrackCollection & tracks ) const

pure virtual

perform truth matching for a given set of tracks
