65 | // Analysis class for azimuthal correlation studies | |
66 | // Based on the UE task from Sara Vallero and Jan Fiete | |
67 | // | |
68 | // This class needs input AODs. | |
69 | // The output is a list of analysis-specific containers. | |
70 | // | |
71 | // The AOD can be either connected to the InputEventHandler | |
72 | // for a chain of AOD files | |
73 | // or | |
74 | // to the OutputEventHandler | |
75 | // for a chain of ESD files, | |
76 | // in this case the class should be in the train after the jet-finder | |
77 | // | |
