18// Compute PID weights for all the clusters that are in AliESDs.root file
19// the AliESDs.root have to be in the same directory as the class
20//
21// and do:
22// AliEMCALPIDUtils *pid = new AliEMCALPIDUtils();
23// pid->SetPrintInfo(kTRUE);
24// pid->SetHighFluxParam(); // pid->SetLowFluxParam();
25//
26// then in cluster loop do
27// pid->ComputePID(energy, lambda0);
28//
29// Compute PID Weight for all clusters in AliESDs.root file
30// keep this function for the moment for a simple verification, could be removed
31//
32// pid->GetPIDFinal(idx) gives the probabilities
33//
34// Double_t PIDFinal[AliPID::kSPECIESN] is the standard PID for :

49// PID[3] is a simple PID for
50// Electron & Photon PID[0]
