38 | // Description: dummy hit class used in reconstruction (derived from AliHit) | |
39 | // For a given TOF hit, the class contains: | |
40 | // - the distance to the nearest hit | |
41 | // - flag for first or second track crossing | |
42 | // - number of the track which produced the hit | |
43 | // - flag for noise | |
