1  From a vector dominance fit to the Born cross section between 1.05 and 2.0 GeV with ${{\mathit \rho}{(770)}}$, ${{\mathit \rho}{(1570)}}$, ${{\mathit \rho}{(1700)}}$, ${{\mathit \rho}{(2150)}}$. The fit also uses SND data from the VEPP-2M collider below 1.02 GeV and from LEES 2017H and ABLIKIM 2021A above 1.5GeV.
2  From a phenomenological model based on vector meson dominance with the interfering ${{\mathit \rho}{(1450)}}$ and ${{\mathit \rho}{(1700)}}$ and their widths fixed at 400 and 250 MeV, respectively. Systematic uncertainty not estimated.
3  Taking into account both ${{\mathit \rho}{(1450)}}$ and ${{\mathit \rho}{(1700)}}$ contributions. Using the data of ACHASOV 2000I on ${{\mathit e}^{+}}$ ${{\mathit e}^{-}}$ $\rightarrow$ ${{\mathit \omega}}{{\mathit \pi}^{0}}$ and of EDWARDS 2000A on ${{\mathit \tau}^{-}}$ $\rightarrow$ ${{\mathit \omega}}{{\mathit \pi}^{-}}{{\mathit \nu}_{{{\tau}}}}$. ${{\mathit \rho}{(1450)}}$ mass and width fixed at 1400 MeV and 500 MeV respectively.
4  Taking into account the ${{\mathit \rho}{(1700)}}$ contribution only. Using the data of ACHASOV 2000I on ${{\mathit e}^{+}}$ ${{\mathit e}^{-}}$ $\rightarrow$ ${{\mathit \omega}}{{\mathit \pi}^{0}}$ and of EDWARDS 2000A on ${{\mathit \tau}^{-}}$ $\rightarrow$ ${{\mathit \omega}}{{\mathit \pi}^{-}}{{\mathit \nu}_{{{\tau}}}}$.
