 Load event into Pythia Common Block

 Load event into Pythia Common Block

  Calls the Pythia jet finding algorithm to find jets in the current event



  Save jets

  Calls the Pythia clustering algorithm to find jets in the current event

 Calculates time of the next subevent

 Is particle in Central Barrel acceptance?
 etamin=-etamax

 Is particle in EMCAL acceptance?
 phi in degrees, etamin=-etamax

 Is particle in PHOS acceptance?
 Acceptance slightly larger considered.
 phi in degrees, etamin=-etamax
 iparticle is the index of the particle to be checked, for PHOS rotation case

Rotate event in phi to enhance events in PHOS acceptance

 use this method only with Perugia-0 tune!

 Check if this is a heavy flavor decay product

 check the eta/phi correspond to the detectors acceptance
 iparticle is the index of the particle to be checked, for PHOS rotation case

 Select events with fragmentation photon, decay photon, pi0, eta or other hadrons going to PHOS or EMCAL or central barrel,
 implemented primaryly for kPyJets, but extended to any kind of process.
