12///
5398f946 13/// MUON class for MonteCarlo Hits, inherited from AliHit for the
692de412 14/// In addition to the ALiHit data member fX, fY, fZ and fTrack, AliMUONHit contains some info about the particle crossing the chamber:
15/// Impulsion: fPtot, fPx, fPy and fPz
16/// Reference position at the center of the chamber (wire plane) fXref, fYref and fZref
17/// Cumulated path along the active volume fTlength for spliting of hits for very inclined tracks
18/// Energy loss of the particle inside the gas active volume.
19/// Incident fTheta and fPhi angle with respect of the wire plane of the chamber.
