16 | // The class AliCFTrackQualityCuts is designed to select reconstructed tracks | |
17 | // of high quality and to provide corresponding QA histograms. | |
18 | // This class inherits from the Analysis' Framework abstract base class | |
19 | // AliAnalysisCuts and is a part of the Correction Framework. | |
20 | // This class acts on single, reconstructed tracks, it is applicable on | |
21 | // ESD and AOD data. | |
22 | // It mainly consists of a IsSelected function that returns a boolean. | |
23 | // This function checks whether the considered track passes a set of cuts: | |
24 | // - number of clusters in the TPC | |
25 | // - number of clusters in the ITS | |
26 | // - chi2 / cluster in the TPC | |
27 | // - chi2 / cluster in the ITS | |
563113d0 | 28 | // - covariance matrix diagonal elements |
8edd0c2c | 29 | // - track status (cf AliESDtrack.h) |
563113d0 | 30 | // |
31 | // The cut values for these cuts are set with the corresponding set functions. | |
32 | // All cut classes provided by the correction framework are supposed to be | |
33 | // added in the Analysis Framwork's class AliAnalysisFilter and applied by | |
34 | // the filter via a loop. | |
