9 // Class for the analysis of high pT pi0 event by event
10 // Pi0 identified by one of the following:
11 // -Invariant mass of 2 cluster in calorimeter
12 // -Shower shape analysis in calorimeter
13 // -Invariant mass of one cluster in calorimeter and one photon reconstructed in TPC (in near future)
