1  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.
2  From a fit to ${{\mathit \omega}}{{\mathit \pi}^{+}}{{\mathit \pi}^{-}}$ with a Breit-Wigner resonance interfering with the continuum.
3  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.
4  From the combined analysis of ANISOVICH 2000D, ANISOVICH 2001C, and ANISOVICH 2002B.
