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
28//
