1  From the Dalitz plot analysis including various ${{\mathit K}^{*}}$ and ${{\mathit D}^{**}}$ mesons as well as broad structures in the ${{\mathit K}}{{\mathit \pi}}{\mathit S}{\mathrm -wave}$ and the ${{\mathit D}}{{\mathit \pi}}$ $\mathit S$- and ${\mathit P}{\mathrm -wave}$s.
2  Modeling the ${{\mathit \pi}^{+}}{{\mathit \pi}^{-}}{\mathit S}{\mathrm -wave}$ with the Isobar formalism.
3  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.
4  At a fixed width of 50.5 MeV.
5  Modeling the ${{\mathit \pi}^{+}}{{\mathit \pi}^{-}}{\mathit S}{\mathrm -wave}$ with the K-matrix formalism.
6  Fit includes the contribution from ${{\mathit D}_{{{0}}}^{*}{(2400)}^{\pm}}$. Not independent of the corresponding mass difference measurement, (${\mathit m}_{{{\mathit D}_{{{2}}}^{*}{(2460)}^{\pm}}}$) $−$ (${\mathit m}_{{{\mathit D}_{{{2}}}^{*}{(2460)}^{0}}}$).
