// ESD and AOD data.
// It mainly consists of a IsSelected function that returns a boolean.
// This function checks whether the considered track passes a set of cuts:
-// - distance to main vertex in units of sigma (resolution)
+// - min. and max. distance to main vertex in transverse plane (xy)
+// - min. and max. longitudinal distance to main vertex (z)
+// - min. and max. distance to main vertex as ellpise in xy - z plane
+// - all above cuts on absolute values or in units of sigma (resolution)
+// - min. and max. distance to main vertex in units of sigma (resolution)
+// - max. transverse (xy) and longitudinal (z) impact parameter resolution
// - require that the dca calculation doesn't fail
// - accept or not accept daughter tracks of kink decays
//
+// By default, the distance to 'vertex calculated from tracks' is used.
+// Optionally the SPD (tracklet based) or TPC (TPC only tracks based) vertex
+// can be used.
+// Note: the distance to the TPC-vertex is already stored in the ESD,
+// the distance to the SPD-vertex has to be re-calculated by propagating each
+// track while executing this cut.
+//
// The cut values for these cuts are set with the corresponding set functions.
// All cut classes provided by the correction framework are supposed to be
// added in the Analysis Framwork's class AliAnalysisFilter and applied by
