1  From a fit to the ${{\mathit e}^{+}}{{\mathit e}^{-}}$ cross section between 2.00 and 3.08 GeV with a sum of Breit-Wigner amplitude and a non-resonant contribution.
2  From a fit to ${{\mathit \omega}}{{\mathit \pi}^{+}}{{\mathit \pi}^{-}}$ and ${{\mathit \omega}}{{\mathit \pi}^{0}}{{\mathit \pi}^{0}}$ with a Breit-Wigner resonance interfering with the continuum. Supersedes ABLIKIM 2022I.
3  From a fit to the cross section between 2.00 and 3.08 GeV with a coherent sum of Breit-Wigner amplitudes, including contributions from ${{\mathit \omega}{(1420)}}$ and ${{\mathit \omega}{(1650)}}/{{\mathit \phi}{(1680)}}$.
4  From a fit to ${{\mathit \omega}}{{\mathit \pi}^{+}}{{\mathit \pi}^{-}}$ with a Breit-Wigner resonance interfering with the continuum.
5  From the fit to the cross section by the coherent sum of resonant component parametrized by a modified Breit-Wigner amplitude and a phase-space contribution for the continuum.
6  From the combined analysis of ANISOVICH 2000D, ANISOVICH 2001C, and ANISOVICH 2002B.
