20 | // MUON event reconstructor in ALICE | |
21 | // | |
22 | // This class contains as data: | |
23 | // * the parameters for the event reconstruction | |
24 | // * a pointer to the array of hits to be reconstructed (the event) | |
25 | // * a pointer to the array of segments made with these hits inside each station | |
26 | // * a pointer to the array of reconstructed tracks | |
27 | // | |
28 | // It contains as methods, among others: | |
29 | // * MakeEventToBeReconstructed to build the array of hits to be reconstructed | |
30 | // * MakeSegments to build the segments | |
31 | // * MakeTracks to build the tracks | |
