1  ACKERSTAFF 1998E systematic error includes an uncertainty of $\pm0.0069$ due to the branching ratios B( ${{\mathit D}^{*+}}$ $\rightarrow$ ${{\mathit D}^{0}}{{\mathit \pi}^{+}}$ ) = $0.683$ $\pm0.014$ and B( ${{\mathit D}^{0}}$ $\rightarrow$ ${{\mathit K}^{-}}{{\mathit \pi}^{+}}$ ) = $0.0383$ $\pm0.0012$.
