Detailed Description

The last step of the electron and photon reconstruction algorithm. The algorithm builds physics objects (xAOD::Electron, xAOD::Photon) from the egammaRec containers built by the previous algorithms. In the step of the chain electron and photon reconstruction are merged again and the ambiguity resolution is applied.

Input collections:

• InputElectronRecCollectionName: default=ElectronSuperRecCollection. A container of egammaRec for electrons
• InputPhotonRecCollectionName: default=PhotonSuperRecCollection. A container of egammaRec for photons

Output collections:

• ElectronOutputName: default=ElectronContainer. A container of xAOD::Electron.
• PhotonOutputName: default=PhotonContainer. A container of xAOD::Photon

If the algorithm runs on both electrons and photons, which is the default (see doPhotons and doElectrons properties), the ambiguity resolution is applied. If there are two egammaRec, one coming from the electron input container, one coming from the photon input container, with the same eta and phi of the hottest cells then the ambiguity tool decides if to save only one or both. The author and the ambiguityType are set accordingly to that decision. If both particles are saved a link between them is saved (ambiguityLink). All the properties of electrons are set:

• cluster links
• track links
• charge
• TrackCaloMatchValues for all the layers, e.g. xAOD::EgammaParameters::deltaEta0, xAOD::EgammaParameters::deltaPhi0, xAOD::EgammaParameters::deltaPhiRescaled0
• xAOD::EgammaParameters::deltaPhiFromLastMeasurement

All the properties of photons are set:

• cluster links
• vertex links
• xAOD::EgammaParameters::convMatchDeltaEta1, xAOD::EgammaParameters::convMatchDeltaPhi1

Several tools are then applied to the particle:

• Shower shapes are computed thanks to the tool configured by EMShowerTool property, implementing the interface IEMShowerBuilder, by default EMShowerBuilder.
• Object quality is filled by the tool specified by the property ObjectQualityTool (no default). If the property is not set object quality is skipped.
• finalize the cluster with the tool specified by the property EMClusterTool (default=EMClusterTool), for example applying energy calibration
• tools specified by the properties egammaTools, ElectronTools, PhotonTools are executed (default: none)
