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