19 | // Hit impact class for PHOS | |
20 | // A hit impact in PHOS is a set of parameters of a track which | |
21 | // enters the detector for the first time. | |
22 | // Track parameters are: | |
23 | // - track number | |
24 | // - primary particle number | |
25 | // - type of a particle | |
26 | // - impact coordinate | |
27 | // - impact 4-momentum | |
