Detailed Description

Class describing a photon reconstructed in the HLT

The HLT reconstructs photons in a simplified manner before using parts of the offline software to reconstruct photons in a manner that's very similar to what the offline reconstruction is doing.

Member Function Documentation

double xAOD::TrigPhoton_v1::e ( ) const [virtual]

The total energy of the particle.

This function gets the energy of the electron using the internal TLorentzVector. Which calculates the energy based on the eta, phi, pt, and m properties.

Returns:: The energy of the electron

Implements xAOD::IParticle.

setRcore setEtHad setFside setPt setCaloPhi const TrigEMCluster * xAOD::TrigPhoton_v1::emCluster ( ) const

The associated EM cluster, as a simple pointer.

This function can be used to conveniently access the EM cluster associated with the electron. It will return a null pointer if the associated object can't be retrieved, but it will never fail in any other way.

Returns:: A pointer to the associated EM cluster, or a null pointer if the object can't be found

const TrigPhoton_v1::FourMom_t & xAOD::TrigPhoton_v1::p4 ( ) const [virtual]

The full 4-momentum of the particle.

This is one of the trickier functions. It provides the 4-momentum of the object as a TLorentzVector. It does this by caching such an object internally, and returning a reference to this cached object.

Returns:: The full 4-momentum of the electron

Implements xAOD::IParticle.

double xAOD::TrigPhoton_v1::rapidity ( ) const [virtual]

The true rapidity (y) of the particle.

This function gets the rapidity of the electron using the internal TLorentzVector. Which calculates the rapidity based on the eta, phi, pt, and m properties.

Returns:: The rapidity (y) of the electron

Implements xAOD::IParticle.
