Goodness of fit:

The total $\chi^{2}$ and number of degrees of freedom is used for $\Lambda ^{0}_{b}$ and $\overline{B^{0}}$ to determine goodness of fit:

• $\Lambda ^{0}_{b}$ : $N d.o.f = 88$, $\chi^{2}_{tot} = 80.6$, so $70\%$ of fits have a worse $\chi^{2}$.
• $\overline{B^{0}}$ : $N d.o.f = 94$, $\chi^{2}_{tot} = 70.9$, so $96\%$ of fits have a worse $\chi^{2}$.
