1  From the fit of the ${{\mathit M}}({{\mathit D}^{0}}{{\mathit \pi}^{+}}$) distribution. The widths of the ${{\mathit D}_{{{1}}}^{+}}$ and ${{\mathit D}_{{{2}}}^{*+}}$ are fixed to 25 MeV and 37 MeV, and A$_{{{\mathit D}_{{{1}}}}}$ and A$_{{{\mathit D}_{{{2}}}}}$ are fixed to the theoretical predictions of 3 and $-1$, respectively.
