18 | // Class for the analysis of gamma-jet correlations | |
e8daeb92 | 19 | // Basically it seaches for a prompt photon in the PHOS acceptance, |
20 | // if so we construct a jet around the highest pt particle in the opposite | |
21 | // side in azimuth, inside the TPC and EMCAL acceptances. First the leading | |
22 | // particle and then the jet have to fullfill several conditions | |
23 | // (energy, direction ..) to be accepted. Then the fragmentation function | |
24 | // of this jet is constructed | |
