18// //
19// Class to analyse tracks for calibration //
20// to be used as a component in AliTPCSelectorTracks //
21// In the constructor you have to specify name and title //
22// to get the Object out of a file. //
23// The parameter 'clusterParam', a AliTPCClusterParam object //
24// (needed for TPC cluster error and shape parameterization) //
25// Normally you get this object out of the file 'TPCClusterParam.root' //
26// In the parameter 'cuts' the cuts are specified, that decide //
27// weather a track will be accepted for calibration or not. //
28// //
29//
30// The data flow:
31//
32/*
33 Raw Data -> Local Reconstruction -> Tracking -> Calibration -> RefData (component itself)
34 Offline/HLT Offline/HLT OCDB entries (AliTPCClusterParam)
