16 | // Class AliEMCALTracker | |
17 | // ----------------------- | |
18 | // Implementation of the track matching method between barrel tracks and | |
19 | // EMCAL clusters. | |
20 | // Besides algorithm implementation, some cuts are required to be set | |
21 | // in order to define, for each track, an acceptance window where clusters | |
22 | // are searched to find best match (if any). | |
23 | // The class accepts as input an ESD container, and works directly on it, | |
24 | // simply setting, for each of its tracks, the fEMCALindex flag, for each | |
25 | // track which is matched to a cluster. | |
26 | // In order to use method, one must launch PropagateBack(). | |
27 | // | |
