14 | // Hit impact class for PHOS | |
15 | // A hit impact in PHOS is a set of parameters of a track which | |
16 | // enters the detector for the first time. | |
17 | // Track parameters are: | |
18 | // - track number | |
19 | // - primary particle number | |
20 | // - type of a particle | |
21 | // - impact coordinate | |
22 | // - impact 4-momentum | |
