18 | // Class that contains the algorithm for the reconstruction of jet, cone around leading particle | |
19 | // The seed is a backward particle (direct photon) | |
20 | // 1)Take the trigger particle stored in AliAODPWG4ParticleCorrelation, | |
21 | // 2) Search for the highest pt leading particle opposite to the photon within a phi, pt window | |
22 | // 3) Take all particles around leading in a cone R with pt larger than threshold and construct the jet | |
23 | // | |
24 | // Class created from old AliPHOSGammaJet | |
