9 // Analysis class for Underlying Event studies w.r.t. leading track
11 // Look for correlations on the tranverse regions w.r.t
12 // the leading track in the event
14 // This class needs input AODs.
15 // The output is a list of analysis-specific containers.
17 // The AOD can be either connected to the InputEventHandler
18 // for a chain of AOD files
20 // to the OutputEventHandler
21 // for a chain of ESD files,
22 // in this case the class should be in the train after the jet-finder
