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. //
33 Raw Data -> Local Reconstruction -> Tracking -> Calibration -> RefData (component itself)
34 Offline/HLT Offline/HLT OCDB entries (AliTPCClusterParam)
39 How to retrive it from file (created using calibration task):
41 gSystem->Load("libANALYSIS");
42 gSystem->Load("libTPCcalib");
43 TFile fcalib("CalibObjects.root");
44 TObjArray * array = (TObjArray*)fcalib.Get("TPCCalib");
45 AliTPCcalibTracks * calibTracks = ( AliTPCcalibTracks *)array->FindObject("calibTracks");
