Hi Elisabetta,


could you try to use the PndKinFitter instead and compare? It works like this:

PndKinFitter fitter(Ds2535[j]);
fitter.Add4MomConstraint(ini);	
fitter.Fit();	
			
double chi2_4c = fitter.GetChi2();
double prob_4c = fitter.GetProb();
			
if ( prob_4c > 0.01 )
{
    RhoCandidate *dstarfit = Ds2535[j]->Daughter(0)->GetFit();
...
}



Best,
Klaus
