For the full field, with ideal tracking, the efficiency goes down only a little (for lambdas from 15.2% to 14.9%) with PndKinVtxFitter, after changing the criterion from
if (prob_vtx>0.0002) // as in the talk
to
bool checkb=vtxfitterlb.Fit();
if(checkb) //current cut
With the PndVtxPRG and with if (prob_vtx>0.0002) for PndKinVtxFitter it goes down more (with the same amount, is that a coincidence?)
