2 | // How to steer the basic TRD data containers from a macro. | |
3 | // | |
4 | // The loading and looping over events is performed by the | |
5 | // AliEve mechanism. For a stand alone TRD loop control check | |
6 | // the macro "trd_loader.C" | |
7 | // | |
8 | // Usage: | |
9 | // .x trd_detectors.C(sector) | |
10 | // | |
11 | // Author: | |
