1  ${{\mathit D}_{{{s}}}^{+}}{{\mathit D}_{{{s}}}^{-}}$ near-threshold enhancement parameterized with a Flatte-like function .
2  Obtained from the full amplitude analysis. Parameterized with the relativistic Breit-Wigner line shape.
3  ${{\mathit \omega}}{{\mathit J / \psi}}$ threshold enhancement fitted as an S-wave Breit-Wigner resonance.
4  Not distinguished from the ${{\mathit \chi}_{{{c2}}}{(3930)}}$.
5  Could also be ${{\mathit X}{(3940)}}$. Significance 3.1$\sigma $. Fit with additional resonance at $3963.7$ $\pm5.7$ MeV, significance 3.4$\sigma $.
