class AliAnalysisTaskPhiCorrelations: public AliAnalysisTask
Analysis class for azimuthal correlation studies
Based on the UE task from Sara Vallero and Jan Fiete
This class needs input AODs.
The output is a list of analysis-specific containers.
The AOD can be either connected to the InputEventHandler
for a chain of AOD files
or
to the OutputEventHandler
for a chain of ESD files,
in this case the class should be in the train after the jet-finder
