1  From a fit of the ${{\mathit D}_{{s}}^{+}}$ recoil mass distribution with an incoherent sum of the ${\mathit S}{\mathrm -wave}$ and ${\mathit D}{\mathrm -wave}$ Breit-Wigner line shapes.
2  Using the ${{\mathit D}^{*}{(2010)}^{\pm}}$ mass of $2010.0$ $\pm0.4$ MeV from PDG 2006 .
3  Calculated using ${\mathit m}_{\mathrm {}}({{\mathit D}^{*}{(2010)}^{\pm}}$) = $2010.0$ $\pm0.5$ MeV, ${\mathit m}_{\mathrm {}}({{\mathit D}^{*}{(2007)}^{0}}$) = $2006.7$ $\pm0.5$ MeV, and the mass difference below.
4  Systematic uncertainties not evaluated.
5  Calculated using the mass difference ${\mathit m}_{\mathrm {}}({{\mathit D}_{{s1}}^{+}})−$ ${\mathit m}_{\mathrm {}}({{\mathit D}^{*+}})_{PDG}$ below and ${\mathit m}_{\mathrm {}}({{\mathit D}^{*+}})_{PDG}$ = $2010.25$ $\pm0.14$ MeV. Assuming ${\mathit S}{\mathrm -wave}$ decay of the ${{\mathit D}_{{s1}}{(2536)}}$ to ${{\mathit D}^{*+}}{{\mathit K}_S^0}$ , using a Breit-Wigner line shape corresponding to L=0.
6  Calculated using the mass difference $\mathit m({{\mathit D}_{{s1}}^{+}}$) $−$ $\mathit m({{\mathit D}^{*+}})_{PDG}$ reported below and $\mathit m({{\mathit D}^{*+}})_{PDG}$ = $2010.27$ $\pm0.17$ MeV.
7  Calculated using ${\mathit m}_{\mathrm {}}({{\mathit D}^{*}{(2007)}^{0}})=2006.6$ $\pm0.5$ MeV and the mass difference below.
8  Calculated using ${\mathit m}_{\mathrm {}}({{\mathit D}^{*}{(2010)}^{\pm}})=2010.1$ $\pm0.6$ MeV and the mass difference below.
9  Not seen in ${{\mathit D}^{*}}{{\mathit K}}$ .
