18 // Class for PID selection with calorimeters
19 // The Output of the 2 main methods GetPdg is a PDG number identifying the cluster,
20 // being kPhoton, kElectron, kPi0 ... as defined in the header file
21 // - GetPdg(const TString calo, const Double_t * pid, const Float_t energy)
22 // Reads the PID weights array of the ESDs and depending on its magnitude identifies the particle
23 // - GetPdg(const TString calo,const TLorentzVector mom, const AliVCluster * cluster)
24 // Recalcultes PID, the bayesian or any new one to be implemented in the future
25 // Right now only the possibility to recalculate EMCAL with bayesian and simple PID.
26 // In order to recalculate Bayesian, it is necessary to load the EMCALUtils library
27 // and do SwitchOnBayesianRecalculation().
28 // To change the PID parameters from Low to High like the ones by default, use the constructor
30 // where flux is AliCaloPID::kLow or AliCaloPID::kHigh
31 // If it is necessary to change the parameters use the constructor
32 // AliCaloPID(AliEMCALPIDUtils *utils) and set the parameters before.
33 // - SetPIDBits: Simple PID, depending on the thresholds fDispCut fTOFCut and even the
34 // result of the PID bayesian a different PID bit is set.
36 // All these methods can be called in the analysis you are interested.
