1  GIBBONS 1997B from charm counting using B(${{\mathit D}_{{{s}}}^{+}}$ $\rightarrow$ ${{\mathit \phi}}{{\mathit \pi}}$) = $0.036$ $\pm0.009$ and B(${{\mathit \Lambda}_{{{c}}}^{+}}$ $\rightarrow$ ${{\mathit p}}{{\mathit K}^{-}}{{\mathit \pi}^{+}}$) = $0.044$ $\pm0.006$.
2  From the difference between ${{\mathit K}^{-}}$ and ${{\mathit K}^{+}}$ widths. ALAM 1987B measurement relies on lepton-kaon correlations. It does not consider the possibility of ${{\mathit B}}{{\overline{\mathit B}}}$ mixing. We have thus removed it from the average.
