29 | * This class builds AliTPCtrack objects from generated tracks to feed * | |
30 | * ITS tracking (V2). The AliTPCtrack is built from its first hit in * | |
31 | * the TPC. The track is assigned a Kalman-like covariance matrix * | |
32 | * depending on its pT and pseudorapidity and track parameters are * | |
70521312 | 33 | * smeared according to this covariance matrix. * |
6eb69b9a | 34 | * Output file contains sorted tracks, ready for matching with ITS. * |
6eb67451 | 35 | * * |
e130146c | 36 | * For details: * |
37 | * http://www.pd.infn.it/alipd/talks/soft/adIII02/TPCtrackingParam.htm * | |
38 | * * | |
39 | * Test macro is: AliBarrelRec_TPCparam.C * | |
6eb67451 | 40 | * * |
6eb69b9a | 41 | * 2002/04/28: Major upgrade of the class * |
42 | * - Covariance matrices and pulls are now separeted for pions, kaons * | |
43 | * and electrons. * | |
44 | * - A parameterization of dE/dx in the TPC has been included and it is * | |
45 | * used to assign a mass to each track according to a rough dE/dx PID. * | |
46 | * - All the "numbers" have been moved to the file with the DataBase, * | |
47 | * they are read as objects of the class AliTPCkineGrid, and assigned * | |
48 | * to data memebers of the class AliTPCtrackerParam. * | |
49 | * - All the code necessary to create a BataBase has been included in * | |
50 | * class (see the macro AliTPCtrackingParamDB.C for the details). * | |
