23//
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.
