- Add photonResoTask.cxx which creates histograms to compare reconstructed vs true photon pT vs cent for EMCal and PCM. Also for EMCal check pi0 and eta rec pT vs true pT vs rec. mass vs cent - Add `IsConversionPointInAcceptance` function to V0PhotonCut.h This function has another definition in MCUtilities.h, however, there the function does multiple other checks as well that are not clear from the name of the function. - Add `isMotherPDG` function that checks for a given mcparticle and a given PDG code, if that particle has a mother within the chain that matches the PDG code.
