Hi,
I am looking in the channel psi(4160)->D0-antiD0 etc.
I am trying to apply 4C fit in psi(4160).
So what I add in my macro is:
PndKinFitter fitter(psi4160[j]);
fitter.Add4MomConstraint(ini); // set 4 constraint
fitter.Fit();
RhoCandidate *d0fit = psi4160[j]->Daughter(0)->GetFit(); // get fitted D0
RhoCandidate *antid0fit = psi4160[j]->Daughter(1)->GetFit(); // get fitted antiD0
npsi4160->Column("d0fit", (Float_t) d0fit->M());
npsi4160->Column("antid0fit", (Float_t) antid0fit->M());
When I run my macro I get something like this:
Error in <TDecompLU::DecomposeLUCrout>: matrix is singular
Error in <TDecompLU::InvertLU>: matrix is singular, 0 diag elements < tolerance of 2.2204e-16
It is the same going over and over again.
Is there something wrong???
