9 | // Hit impact class for PHOS | |
10 | // A hit impact in PHOS is a set of parameters of a track which | |
11 | // enters the detector for the first time. | |
12 | // Track parameters are: | |
13 | // - track number | |
14 | // - primary particle number | |
15 | // - type of a particle | |
16 | // - impact coordinate | |
17 | // - impact 4-momentum | |
