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