bdd2a262 | 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 | |
0ae57829 | 23 | // - GetPdg(const TString calo,const TLorentzVector mom, const AliVCluster * cluster) |
bdd2a262 | 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 | |
29 | // AliCaloPID(flux) | |
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. | |
35 | // | |
36 | // All these methods can be called in the analysis you are interested. | |
