Hi, the problem is, if I am getting more reconstructed photons than generated, how can I relate them. I mean, If I want to have the energy difference between the generated i,e 1 GeV and reconstructed, how it is possible ? As per my knowledge, if a single photon hits the EMC crystal, the digitized output should give a single cluster which will estimate the energy of the primary photon. Thus for 100 primary photons, it should have 100 emc cluster and their energy accordingly. Please correct me if I am wrong.
regards
Kamal Dutta

But I am worried about the part above 1 GeV. How to estimate these values. If I want to estimate reconstructed photon energy for each of the primary photon and its start vertex of EM shower, how it is possible in this situation. The start vertex I calculated for 100 events using PndMCIndex. On the other hand, I got 202 reconstructed photon events from PndPidCandidate. It really puzzled me.
