17// AliT0hit is the hit class for the T0. Hits are the information
18// that comes from a Monte Carlo at each step as a particle mass through
19// sensitive detector elements as particles are transported through a
20// detector.
21//
22// Data members:
23//
24// Int_t fTrack
25// See AliHit for a full description. The track number of the track
26// that made this hit.
27//
28// Float_t fX
29// See AliHit for a full description. The global x position of the
30// hit (in the standard units of the Monte Carlo).
31//
32// Float_t fY
33// See AliHit for a full description. The global y position of the
34// hit (in the standard units of the Monte Carlo).
35//
36// Float_t fZ
37// See AliHit for a full description. The global z position of the
38// hit (in the standard units of the Monte Carlo).
39//
40// Int_t fStatus
41// The track status flag. This flag indicates the track status
42// at the time of creating this hit. It is made up of the following 8
43// status bits from highest order to lowest order bits
44// 0 : IsTrackAlive(): IsTrackStop():IsTrackDisappeared():
45// IsTrackOut():IsTrackExiting():IsTrackEntering():IsTrackInside() .
46// See AliMC for a description of these functions. If the function is
47// true then the bit is set to one, otherwise it is zero.
48//
49// Int_t fVolume
50// The number of the T0 detector that contains this hit.
51// 0 - right array; 1 - left array
52// Int_t fPmt
53// the number of PMT tube that contains hit
54// Float_t fEdep
55// The energy lost by the particle during the step ending in this
56// hit. The units are those determined by the Monte Carlo.
57//
58// Float_t fTime
59// The time of flight associated with the particle in this
60// hit. The time is typically measured from the point of creation of the
61// original particle (if this particle is a daughter). The units
62// are those determined by the Monte Carlo.
