Data formats in RecoEgamma

Complete: 5 Event content definition

InputTag/Module (Instance name) Containers Description

Egamma electron collections (in RECO and AOD)
gsfElectronCores reco::GsfElectronCoreCollection Offline electron object containing a minimal set of information: reference to GsfTrack, reference to SuperCluster (Egamma and/or PFlow cluster) and provenance information. The collection is unpreselected and contains electrons reconstructed either by Egamma or by PF algorithm.
gsfElectrons reco::GsfElectronCollection Offline electron containing all the relevant observables and corrections. The collection is produced starting from GsfElectronCore and its modularity allows to easily recompute electron variables skipping the reconstruction step. Each electron has also a reference to the corresponding "core" partner. (standard offline electron collection)
electronGsfTracks reco::GsfTrackCollection GsfTracks for GsfElectrons (produced in a dedicated module in the standard reconstruction sequence). They have been produced from the electronMergedSeeds described below.
eidTYPE   ValueMaps containing a reference to a CMS.GsfElectron and the result of the electron ID. The event has one Value Map per identification TYPE (eidLoose, eidRobust...) (standard electron ID computed in standard sequence)
siStripElectronToTrackAssociator reco::ElectronCollection Electrons reconstructed using tracks seeded in the Si strip layers (not produced in standard sequence)
egammaCTFFinalFitWithMaterial reco::TrackCollection Tracks for Si strip seeded electrons (not produced in standard sequence)
siStripElectrons reco::SiStripElectronCollection Intermediate object for Si Strip electron reconstruction containing information about Si strip hits associated to the SuperCluster (not produced in standard sequence)
Egamma photon collections (in RECO and AOD)
photonCore reco::PhotonCoreCollection Photon objects containing reference to SuperCluster, Conversions and ElectronSeeds.
photons reco::PhotonCollection Photons with all the related observables like vertex, shower shapes, isolation. Each photon has also a reference to the corresponding "core" partner. (standard reconstructed photon collection)
PhotonIDProd reco::PhotonIDCollection Photons identification variables, calculated for corresponding photons. (standard reconstructed photon collection)
conversions reco::ConversionCollection Converted photons
ckfOutInTracksFromConversions reco::TrackCollection Conversion tracks from outside-in tracking.
ckfInOutTracksFromConversions reco::TrackCollection Conversion tracks from inside-out tracking.
Egamma electron collections (in RECO only)
gsfElectronsGsfFit reco::GsfTrackExtraCollection reco::TrackExtraCollection TrackingRecHitCollection GsfTrackExtras, TrackExtras, TrackingRecHits
electronMergedSeeds reco::ElectronSeedCollection Mixed collection of ElectronSeeds coming from Egamma and/or PFlow algorithms, with their parent SuperClusters and/or tracks. They are used as input for the production of electronGsfTracks.
ecalDrivenElectronSeeds reco::ElectronSeedCollection Collection of ElectronSeeds with their parent SuperClusters, using the SuperCluster driven pixel matching algorithm, made for electron track seeding. That's one of the two collections which are mixed into electronMergedSeeds just above.
egammaCTFFinalFitWithMaterial reco::TrackExtraCollection TrackExtras for Si strip seeded electrons (not produced in standard sequence)
Egamma photon collections (in RECO only)
ckfOutInTracksFromConversions reco::TrackExtraCollection TrackingRecHitCollection TrackExtras and TrackingRecHits for conversion tracks from outside-in tracking.
ckfInOutTracksFromConversions reco::TrackExtraCollection TrackingRecHitCollection TrackExtras and TrackingRecHits for conversion tracks from inside-out tracking.
