18 | // Class for the analysis of gamma (gamma-jet, | |
19 | // gamma-hadron(Arleo, TODO)) | |
20 | // This class only contains 3 methods: one to fill lists of particles (ESDs) comming | |
2a1d8a29 | 21 | // from the CTS (ITS+TPC) and the calorimeters; the other search in the |
f9cea31c | 22 | // corresponing calorimeter for the highest energy cluster, identify it as |
2a1d8a29 | 23 | // prompt photon(Shower Shape and Isolation Cut), the last method does the |
24 | // isolation selection | |
