1  From the combined fit of the ${{\mathit M}}$( ${{\mathit D}^{+}}{{\mathit \pi}^{-}}$ ) and ${{\mathit M}}$( ${{\mathit D}^{*+}}{{\mathit \pi}^{-}}$ ) distributions. and A$_{{{\mathit D}_{{2}}}}$ fixed to the theoretical prediction of $-1$.
2  Fit includes the contribution from ${{\mathit D}_{{1}}^{*}{(2430)}^{0}}$.
3  Calculated using the mass difference $\mathit m({{\mathit D}_{{1}}^{0}}$) $−$ $\mathit m({{\mathit D}^{*+}})_{PDG}$ reported below and $\mathit m({{\mathit D}^{*+}})_{PDG}$ = $2010.27$ $\pm0.17$ MeV. The 0.17 MeV uncertainty of the PDG mass value should be added to the experimental uncertainty of 0.9 MeV.
4  No systematic error given.
