34c512f6 18// MUON classe for MonteCarlo Hits, inherited from AliHit for the
19// In addition to the ALiHit data member fX, fY, fZ and fTrack, AliMUONHit contains some info about the particle crossing the chamber:
20// Impulsion: fPtot, fPx, fPy and fPz
21// Reference position at the center of the chamber (wire plane) fXref, fYref and fZref
22// Cumulated path along the active volume fTlength for spliting of hits for very inclined tracks
23// Energy loss of the particle inside the gas active volume.
24// Incident fTheta and fPhi angle with respect of the wire plane of the chamber.
