24 | // AliITShit is the hit class for the ITS. Hits are the information | |
25 | // that comes from a Monte Carlo at each step as a particle mass through | |
26 | // sensitive detector elements as particles are transported through a | |
27 | // detector. | |
28 | // | |
29 | // Data members: | |
30 | // | |
31 | // Int_t fTrack | |
32 | // See AliHit for a full description. The track number of the track | |
33 | // that made this hit. | |
34 | // | |
35 | // Float_t fX | |
36 | // See AliHit for a full description. The global x position of the | |
37 | // hit (in the standard units of the Monte Carlo). | |
38 | // | |
39 | // Float_t fY | |
40 | // See AliHit for a full description. The global y position of the | |
41 | // hit (in the standard units of the Monte Carlo). | |
42 | // | |
43 | // Float_t fZ | |
44 | // See AliHit for a full description. The global z position of the | |
45 | // hit (in the standard units of the Monte Carlo). | |
46 | // | |
47 | // Int_t fStatus | |
48 | // The track status flag. This flag indicates the track status | |
49 | // at the time of creating this hit. It is made up of the following 8 | |
50 | // status bits from highest order to lowest order bits | |
51 | // 0 : IsTrackAlive(): IsTrackStop():IsTrackDisappeared(): | |
52 | // IsTrackOut():IsTrackExiting():IsTrackEntering():IsTrackInside() . | |
53 | // See AliMC for a description of these functions. If the function is | |
54 | // true then the bit is set to one, otherwise it is zero. | |
55 | // | |
56 | // Int_t fLayer | |
57 | // The layer number of the detector that contains this hit. See | |
58 | // AliITSgeom and AliITSv? for a description of the geometry. | |
59 | // | |
60 | // Int_t fLadder | |
61 | // The ladder number of the detector that contains this hit. See | |
62 | // AliITSgeom and AliITSv? for a description of the geometry. | |
63 | // | |
64 | // Int_t fDet | |
65 | // The detector number of the detector that contains this hit. See | |
66 | // AliITSgeom and AliITSv? for a description of the geometry. | |
67 | // | |
68 | // Float_t fPx | |
69 | // The x momentum, in global coordinates, of the particle that | |
70 | // "created" the hit at the time and position of the hit. The units | |
71 | // are those determined by the Monte Carlo. | |
72 | // | |
73 | // Float_t fPy | |
74 | // The y momentum, in global coordinates, of the particle that | |
75 | // "created" the hit at the time and position of the hit. The units | |
76 | // are those determined by the Monte Carlo. | |
77 | // | |
78 | // Float_t fPz | |
79 | // The z momentum, in global coordinates, of the particle that | |
80 | // "created" the hit at the time and position of the hit. The units | |
81 | // are those determined by the Monte Carlo. | |
82 | // | |
83 | // Float_t fDestep | |
84 | // The energy lost by the particle during the step ending in this | |
85 | // hit. The units are those determined by the Monte Carlo. | |
86 | // | |
87 | // Float_t fTof | |
88 | // The time of flight associated with the particle ending in this | |
89 | // hit. The time is typically measured from the point of creation of the | |
90 | // original particle (if this particle is a daughter). The units | |
91 | // are those determined by the Monte Carlo. | |
