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.
