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.
