// This class allows you to classify a given muon according to defined criteria. For this purpose
|
| 7 |
// is loads histograms from two ROOT files, specified in the constructor. The main function then
|
| 8 |
// is "IsGood(*muon, selection)" which returns true if the given muon fulfills the selection
|
| 9 |
// criteria.
|
| 10 |

// Logically, the code has been put together by Phil who took most of the ideas from
