Data formats in RecoMuon

Event content definition

Muon collections (in RECO and AOD)
muons	reco::MuonCollection	Muons built using tracker-muon, standalone-muon and global-muon reconstruction algorithms with muon id and other information (energy deposits, isolation information, etc.)
muonsFromCosmics	reco::MuonCollection	Similar to "muons" but reconstructed by dedicated cosmic-muon reconstructor (2-leg option)
muonsFromCosmics1Leg	reco::MuonCollection	Similar to "muons" but reconstructed by dedicated cosmic-muon reconstructor (1-leg option)
Muon collections (in RECO only)
calomuons	reco::CaloMuonCollection	Tracks with energy depositions in the calorimeters consistent with those of a muon, but which failed all other muon reconstruction algorithms
muonsWithSET	reco::MuonCollection	Similar to "muons" but reconstructed by alternative SET algorithm for standalone muons
Muon track collections (in RECO and AOD)
standAloneMuons	reco::TrackCollection	Standalone muon tracks without extra and hits
standAloneMuons:UpdatedAtVtx	reco::TrackCollection	Standalone muon tracks without extra and hits, with constraint at the beam spot
cosmicMuons	reco::TrackCollection	Standalone muon tracks reconstructed by dedicated cosmic-muon reconstructor (2-leg option)
cosmicMuons1Leg	reco::TrackCollection	Standalone muon tracks reconstructed by dedicated cosmic-muon reconstructor (1-leg option)
globalMuons	reco::TrackCollection	Global muon tracks without extra and hits
globalCosmicMuons	reco::TrackCollection	Global muon tracks reconstructed by dedicated cosmic-muon reconstructor (2-leg option)
globalCosmicMuons1Leg	reco::TrackCollection	Global muon tracks reconstructed by dedicated cosmic-muon reconstructor (1-leg option)
tevMuons:default	reco::TrackCollection	Global muon tracks using the global-muon reconstruction algorithm with one refit
tevMuons:firstHit	reco::TrackCollection	Global muon tracks using all tracker hits plus hits from the first muon station that has them
tevMuons:picky	reco::TrackCollection	Global muon tracks using all tracker hits plus hits from the muon stations which do not contain electromagnetic showers
tevMuons:dyt	reco::TrackCollection	Global muon tracks reconstructed by the DYT algorithm for high-pT muons
Muon track collections (in RECO only)
standAloneSETMuons	reco::TrackCollection	Similar to standAloneMuons but produced by alternative SET algorithm
globalSETMuons	reco::TrackCollection	Similar to globalMuons but produced by alternative SET algorithm
Muon seeds (in RECO only)
MuonSeed	TrajectorySeed	Seeds for standalone muon reconstruction
CosmicMuonSeed	TrajectorySeed	Seeds for dedicated cosmic reconstructor of standalone muons
Muon isolation collections (in RECO and AOD)
muIsoDepositTk	reco::IsoDepositMap	Map of IsoDeposits for each muon calculated using general tracks
muIsoDepositCalByAssociatorTowers	reco::IsoDepositMap	Map of IsoDeposits for each muon calculated using calorimeter towers. Three instances are created (corresponding to the calo-tower component): ecal, hcal, and ho
muIsoDepositJets	reco::IsoDepositMap	Map of IsoDeposits for each muon calculated using jets (sisCone5CaloJets)
Muon track associations (in RECO and AOD)
tevMuons:default	reco::TrackToTrackMap	Map associating tracks in the globalMuons collection to tracks in the tevMuons:default collection
tevMuons:firstHit	reco::TrackToTrackMap	Map associating tracks in the globalMuons collection to tracks in the tevMuons:firstHit collection
tevMuons:picky	reco::TrackToTrackMap	Map associating tracks in the globalMuons collection to tracks in the tevMuons:picky collection
tevMuons:dyt	reco::TrackToTrackMap	Map associating tracks in the globalMuons collection to tracks in the tevMuons:dyt collection
Other information (in RECO and AOD)
muid*	edm::ValueMap<boolean>	Output of the muon selectors defined in DataFormats/MuonReco/interface/MuonSelectors.h
MuonShowerInformation	edm::ValueMap<reco::MuonShower>	Muon shower information, defined in DataFormats/MuonReco/interface/MuonShower.h
muons	edm::ValueMap<reco::MuonTimeExtra>	Muon timing information for DT, CSC, and combined, defined in DataFormats/MuonReco/interface/MuonTimeExtra.h
cosmicsVeto	edm::ValueMap<unsigned int>	Index of the partner track found in the opposite hemisphere, used by the cosmic-muon identifier
cosmicsVeto	edm::ValueMap<reco::MuonCosmicCompatibility>	Information used by the cosmic-muon identifier, defined in DataFormats/MuonReco/interface/MuonCosmicCompatibility.h

Each reco::TrackCollection has two extra collections associated to it: reco::TrackExtra (both in RECO and AOD for standard reconstructions algorithms, only in RECO for cosmic algorithms) and TrackingRecHitsOwned (both in AOD and in RECO for "standAloneMuons", only in RECO for all other collections). These collections should not be accessed directly but only through the reco::Track methods.
