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, (${\mathit m}_{{{\mathit D}_{{2}}^{*}{(2460)}^{\pm}}}$) $−$ (${\mathit m}_{{{\mathit D}_{{2}}^{*}{(2460)}^{0}}}$).
