Note: This limit assumes the average of B(${{\mathit D}^{0}}$ $\rightarrow$ ${{\mathit K}^{-}}{{\mathit e}^{+}}{{\mathit \nu}_{{{e}}}}$) and B(${{\mathit D}^{0}}$ $\rightarrow$ ${{\mathit K}^{-}}{{\mathit \mu}^{+}}{{\mathit \nu}_{{{\mu}}}}$) for the B(${{\mathit D}^{0}}$ $\rightarrow$ ${{\mathit K}^{-}}{{\mathit \ell}^{+}}{{\mathit \nu}_{{{{{\mathit \ell}}}}}}$) value.
The following data is related to the above value:
$\Gamma({{\mathit D}^{0}}$ $\rightarrow$ ${{\mathit K}^{+}}{{\mathit \ell}^{-}}{{\overline{\mathit \nu}}_{{{{{\mathit \ell}}}}}}$ via ${{\overline{\mathit D}}^{0}})/\Gamma({{\mathit D}^{0}}$ $\rightarrow$ ${{\mathit K}^{-}}{{\mathit \ell}^{+}}{{\mathit \nu}_{{{{{\mathit \ell}}}}}})$
