Isolated photon purity as a function of photon \pT for isolated photon analysis in pp 13TeV. Only consider charge particle in isolation cone and the isolation cut is cone size R=0.4 and pTiso < 1.5 GeV/c. 

Detail description

Using the LHC16,17,18 AOD dataset (MB, G2, G1) and corresponding simulation (GJ, JJlow, JJhigh, JJveryhigh) sample. the analysis used detector is EMCal and DCal. Gamma select shower shape cut is [ 0.1, 0.3 ]. Only consider charge particle in isolation cone and the isolation cut is cone size R=0.4 and pTiso < 1.5 GeV/c.
