combinedTauTag reco::JetTag (lxr cvs) Results of the CombinedTauTag Algorithm. In the Reco content since 1_6_0.
combinedTauTag reco::CombinedTauTagInfo (lxr cvs) CombinedTauTag dedicated TagInfo. The Discriminator is computed on a track isolation criteria and a Likelihood computed on the basis of the neutral activity. In the Reco content since 1_6_0.
tauPFProducer (tauCaloProducer) reco::Tau (lxr cvs) Tau class equivalent to the Muon, Electron and Jet one. Almost all the code for the tagging algorithm is being migrating to use this class as input. In this case the PFConeIsolation is used to fill the relevant variables. In the Reco content since 1_6_0.
pfConeIsolation reco::PFIsolatedTauTagInfo (lxr cvs) Equivalent of the ConeIsolation based tagInfo but made with ParticleFlow objects. The isolation can be computed using charged and neutral particles. In the Reco content since 1_6_0.
