1  From a three-resonance fit to the Born cross section in the range $\sqrt {s }$ = $3.808 - 4.951$ GeV. Supersedes ABLIKIM 2020O.
2  From a three-resonance fit to the dressed cross section in the range $\sqrt {s }$ = $4.128 - 4.950$ GeV.
3  From a cross-section measurement of ${{\mathit e}^{+}}$ ${{\mathit e}^{-}}$ $\rightarrow$ ${{\mathit D}^{*0}}{{\mathit D}^{*-}}{{\mathit \pi}^{+}}$ between 4.189 and 4.951 GeV, assuming a coherent sum of 3 Breit-Wigner resonances plus a continuum amplitude. The two other resonances have masses (widths) $4675.3$ $\pm29.7$ ($218.3$ $\pm73.5$) MeV and $4469.1$ $\pm26.4$ ($246.3$ $\pm37.9$) MeV.
4  From a three-resonance fit to the Born cross section in the range $\sqrt {s }$ = $3.7730 - 4.7008$ GeV.
5  From a two-resonance fit to the dressed cross section in the range $\sqrt {s }$ = $4.127 - 4.600$ GeV. The second resonance has a mass of $4484.7$ $\pm13.3$ $\pm24.1$ MeV and a total width of $111.1$ $\pm30.1$ $\pm15.2$ MeV.
