Initialize the parameters of the PID.

 Select the appropriate mass range for pi0 selection in splitting method
 No used yet in splitting ID decision

 Select the appropriate mass range for pi0 selection in splitting method

 Select the appropriate m02 range, fix cut, not E dependent

 Select the appropriate m02 range in splitting method for pi0

 Select the appropriate m02 range in splitting method to select eta's
 Use same parametrization as pi0, just shift the distributions (to be tuned)

 Select the appropriate m02 range in splitting method for converted photons
 Just min limit for pi0s is max for conversion.

 return pointer to AliEMCALPIDUtils, create it if needed

 Returns a PDG number corresponding to the likely ID of the cluster

Return most probable identity of the particle after bayesian weights calculated in reconstruction

 Split the cluster in 2, do invariant mass, get the mass and decide
 if this is a photon, pi0, eta, ...

Put data member values in string to keep in output container

 print PID of cluster, (AliVCluster*)cluster->GetPID()

Set Bits for PID selection

Check if there is any track attached to this cluster

Check if cluster photon-like. Uses photon cluster parameterization in real pp data
Returns distance in sigmas. Recommended cut 2.5

Checks distance to the closest track. Takes into account
non-perpendicular incidence of tracks.
returns distance in sigmas. Recommended cut: 2.
Requires (sign) of magnetic filed. onc can find it for example as following
  Double_t mf=0. ;
  AliESDEvent *event = dynamic_cast<AliESDEvent*>(InputEvent());
  if(event)
    mf = event->GetMagneticField(); //Positive for ++ and negative for --
