PndKinVtxFitter vtxfitter(etac_vtx[j]);
vtxfitter.Fit();
RhoCandidate *etacfit=etac_vtx[j]->GetFit();
k1 = etacfit->Daughter(0);


k1 is fitted or not?

k1 is fitted.

To understand this concept: The decay tree is copied internally. The fitted tree can be accessed via one call of GetFit(). Then you navigate in the fitted tree via Mother/Daughters relations.

Cheers
