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. //
