28 | // AliESDtrack: | |
29 | // 1. What is the AliESDtrack | |
30 | // 2. What informations do we store | |
31 | // 3. How to use the information for analysis | |
32 | // | |
33 | // | |
34 | // 1.AliESDtrack is the container of the information about the track/particle | |
35 | // reconstructed during Barrel Tracking. | |
36 | // The track information is propagated from one tracking detector to | |
37 | // other using the functionality of AliESDtrack - Current parameters. | |
38 | // | |
39 | // No global fit model is used. | |
40 | // Barrel tracking use Kalman filtering technique, it gives optimal local | |
41 | // track parameters at given point under certian assumptions. | |
42 | // | |
43 | // Kalman filter take into account additional effect which are | |
44 | // difficult to handle using global fit. | |
45 | // Effects: | |
46 | // a.) Multiple scattering | |
47 | // b.) Energy loss | |
48 | // c.) Non homogenous magnetic field | |
49 | // | |
50 | // In general case, following barrel detectors are contributing to | |
51 | // the Kalman track information: | |
52 | // a. TPC | |
53 | // b. ITS | |
54 | // c. TRD | |
55 | // | |
56 | // In general 3 reconstruction itteration are performed: | |
57 | // 1. Find tracks - sequence TPC->ITS | |
58 | // 2. PropagateBack - sequence ITS->TPC->TRD -> Outer PID detectors | |
59 | // 3. Refit invward - sequence TRD->TPC->ITS | |
60 | // The current tracks are updated after each detector (see bellow). | |
61 | // In specical cases a track sanpshots are stored. | |
62 | // | |
63 | // | |
64 | // For some type of analysis (+visualization) track local parameters at | |
65 | // different position are neccesary. A snapshots during the track | |
66 | // propagation are created. | |
67 | // (See AliExternalTrackParam class for desctiption of variables and | |
68 | // functionality) | |
69 | // Snapshots: | |
70 | // a. Current parameters - class itself (AliExternalTrackParam) | |
71 | // Contributors: general case TRD->TPC->ITS | |
72 | // Preferable usage: Decission - primary or secondary track | |
73 | // NOTICE - By default the track parameters are stored at the DCA point | |
74 | // to the primary vertex. optimal for primary tracks, | |
75 | // far from optimal for secondary tracks. | |
76 | // b. Constrained parameters - Kalman information updated with | |
77 | // the Primary vertex information | |
78 | // Contributors: general case TRD->TPC->ITS | |
79 | // Preferable usage: Use only for tracks selected as primary | |
80 | // NOTICE - not real constrain - taken as additional measurement | |
81 | // with corresponding error | |
82 | // Function: | |
83 | // const AliExternalTrackParam *GetConstrainedParam() const {return fCp;} | |
84 | // c. Inner parameters - Track parameters at inner wall of the TPC | |
85 | // Contributors: general case TRD->TPC | |
86 | // function: | |
87 | // const AliExternalTrackParam *GetInnerParam() const { return fIp;} | |
88 | // | |
89 | // d. TPCinnerparam - contributors - TPC only | |
90 | // Contributors: TPC | |
91 | // Preferable usage: Requested for HBT study | |
92 | // (smaller correlations as using also ITS information) | |
93 | // NOTICE - the track parameters are propagated to the DCA to | |
94 | // to primary vertex | |
95 | // Optimal for primary, far from optimal for secondary tracks | |
96 | // Function: | |
97 | // const AliExternalTrackParam *GetTPCInnerParam() const {return fTPCInner;} | |
98 | // | |
99 | // e. Outer parameters - | |
100 | // Contributors- general case - ITS-> TPC -> TRD | |
101 | // The last point - Outer parameters radius is determined | |
102 | // e.a) Local inclination angle bigger than threshold - | |
103 | // Low momenta tracks | |
104 | // e.a) Catastrofic energy losss in material | |
105 | // e.b) Not further improvement (no space points) | |
106 | // Usage: | |
107 | // a.) Tracking: Starting parameter for Refit inward | |
108 | // b.) Visualization | |
109 | // c.) QA | |
110 | // NOTICE: Should be not used for the physic analysis | |
111 | // Function: | |
112 | // const AliExternalTrackParam *GetOuterParam() const { return fOp;} | |
