// Class AliRsnDaughter
//
-// Interface to candidate daughters of a resonance (tracks).
-// Points to the source of information, which is generally an AliVParticle-derived object
-// and contains few internal data-members to store "on fly" some important information
+// Interface to candidate daughters of a resonance (tracks or V0s).
+// It contains two pointers to two AliVParticle-derived objects.
// for the computations required during resonance analysis.
