1  From the fit with two resonances.
2  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 1.5 GeV.
3  From a fit using a two resonance model in which the mass and width of the other resonance are fixed at the ${{\mathit \rho}{(1700)}}$ values from PDG 2020.
4  Systematic errors not estimated.
