75fb37cc | 7 | // Class AliCluster |
8 | // This is the future base for managing the clusters in barrel detectors. | |
9 | // It is fully interfaced with the ROOT geometrical modeller TGeo. | |
10 | // Each cluster contains XYZ coordinates in the local tracking c.s. and | |
11 | // the unique ID of the sensitive detector element which continas the | |
12 | // cluster. The coordinates in global c.s. are computed using the interface | |
13 | // to TGeo and will be not overwritten by the derived sub-detector cluster | |
14 | // classes. | |
