20 | * This class builds AliTPCtrack objects from generated tracks to feed * | |
21 | * ITS tracking (V2). The AliTPCtrack is built from its first hit in * | |
22 | * the TPC. The track is assigned a Kalman-like covariance matrix * | |
23 | * depending on its pT and pseudorapidity and track parameters are * | |
24 | * smeared according to this covariance matrix. * | |
25 | * Output file contains sorted tracks, ready for matching with ITS. * | |
26 | * * | |
27 | * For details: * | |

32 | * 2002/10/01: Introduction of the database for pp collisions (B=0.4 T) * | |
33 | * - Everything done separately for pions, kaons, protons, electrons and * | |
34 | * muons. * | |
35 | * - Now (only for pp) the tracks are built from the AliTrackReferences * | |
36 | * which contain the position and momentum of all tracks at R = 83 cm; * | |
37 | * This eliminates the loss of tracks due the dead zone of the TPC * | |
38 | * where the 1st hit is not created. * | |
39 | * - In AliBarrelRec_TPCparam.C there many possible ways of determining * | |
40 | * the z coordinate of the primary vertex in pp events (from pixels, * | |
41 | * from ITS tracks, smearing according to resolution given by tracks. * | |
42 | * * | |
43 | * 2002/04/28: Major upgrade of the class * | |
44 | * - Covariance matrices and pulls are now separeted for pions, kaons * | |
45 | * and electrons. * | |
46 | * - A parameterization of dE/dx in the TPC has been included and it is * | |
47 | * used to assign a mass to each track according to a rough dE/dx PID. * | |
48 | * - All the "numbers" have been moved to the file with the DataBase, * | |
49 | * they are read as objects of the class AliTPCkineGrid, and assigned * | |
50 | * to data memebers of the class AliTPCtrackerParam. * | |
51 | * - All the code necessary to create a BataBase has been included in * | |
52 | * class (see the macro AliTPCtrackingParamDB.C for the details). * | |
