9 | // Analysis class for Underlying Event studies w.r.t. leading track | |
10 | // | |
11 | // Look for correlations on the tranverse regions w.r.t | |
12 | // the leading track in the event | |
13 | // | |
14 | // This class needs input AODs. | |
15 | // The output is a list of analysis-specific containers. | |
16 | // | |
17 | // The AOD can be either connected to the InputEventHandler | |
18 | // for a chain of AOD files | |
19 | // or | |
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 | |
