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:
89d7d478 25// - min. and max. distance to main vertex in transverse plane (xy)
26// - min. and max. longitudinal distance to main vertex (z)
27// - min. and max. distance to main vertex as ellpise in xy - z plane
28// - all above cuts on absolute values or in units of sigma (resolution)
29// - min. and max. distance to main vertex in units of sigma (resolution)
30// - max. transverse (xy) and longitudinal (z) impact parameter resolution
563113d0 31// - require that the dca calculation doesn't fail
32// - accept or not accept daughter tracks of kink decays
33//
c66800ea 34// By default, the distance to 'vertex calculated from tracks' is used.
c2c45ca4 35// Optionally the SPD (tracklet based) or TPC (TPC only tracks based) vertex
36// can be used.
37// Note: the distance to the TPC-vertex is already stored in the ESD,
38// the distance to the SPD-vertex has to be re-calculated by propagating each
39// track while executing this cut.
c66800ea 40//
563113d0 41// The cut values for these cuts are set with the corresponding set functions.
42// All cut classes provided by the correction framework are supposed to be
43// added in the Analysis Framwork's class AliAnalysisFilter and applied by
44// the filter via a loop.
