Yes, we are using the same data and MC sets, so they should be highly correlated. By less then one sigma I just meant naively looking at the full error from the unfolded spectrum (0.17). > > That the value from the unfolded spectrum is somewhat smaller agrees with > > the fact that we saw the fits for mb and a (in the dFN model, which we > > made last summer) prefer values of mb on the smaller side. > Hm, I'm not fully convinced that this explain > whole the difference.
