16// Implementation of the ESD track class

24// What do you need to know before starting analysis
25// (by Marian Ivanov: marian.ivanov@cern.ch)
26//
27//
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;}
