-// Class for the analysis of gamma-jet correlations.
-// Basically it seaches for a prompt photon in the Calorimeters acceptance,
-// if so we construct a jet around the highest pt particle in the opposite
-// side in azimuth. This jet has to fullfill several conditions to be
-// accepted. Then the fragmentation function of this jet is constructed
-// Class created from old AliPHOSGammaPion
-
+// Class that contains the algorithm for the analysis of gamma - hadron correlations
