17 // Class that contains the algorithm for the reconstruction of jet, cone around leading particle
18 // The seed is a backward particle (direct photon)
19 // 1) Take the trigger particle stored in AliAODPWG4ParticleCorrelation,
20 // 2) Search for the highest pt leading particle opposite to the photon within a phi, pt window
21 // 3) Take all particles around leading in a cone R with pt larger than threshold and construct the jet
23 // Class created from old AliPHOSGammaJet
24 // (see AliRoot versions previous Release 4-09)
