16 | // The class AliCFTrackIsPrimaryCut is designed to select reconstructed tracks | |
17 | // with a small impact parameter and tracks which are (not) daughters of kink | |
18 | // decays and to provide corresponding QA histograms. | |
19 | // This class inherits from the Analysis' Framework abstract base class | |
20 | // AliAnalysisCuts and is a part of the Correction Framework. | |
21 | // This class acts on single, reconstructed tracks, it is applicable on | |
22 | // ESD and AOD data. | |
23 | // It mainly consists of a IsSelected function that returns a boolean. | |
24 | // This function checks whether the considered track passes a set of cuts: | |
25 | // - distance to main vertex in units of sigma (resolution) | |
26 | // - require that the dca calculation doesn't fail | |
27 | // - accept or not accept daughter tracks of kink decays | |
28 | // | |
29 | // The cut values for these cuts are set with the corresponding set functions. | |
30 | // All cut classes provided by the correction framework are supposed to be | |
31 | // added in the Analysis Framwork's class AliAnalysisFilter and applied by | |
32 | // the filter via a loop. | |
33 | // | |
34 | // author: I. Kraus (Ingrid.Kraus@cern.ch) | |
35 | // idea taken form | |
36 | // AliESDtrackCuts writte by Jan Fiete Grosse-Oetringhaus and | |
