From the combined fit of AULCHENKO 2015 and ACHASOV 2018 in the model with the interfering ${{\mathit \rho}{(1450)}}$, ${{\mathit \rho}{(1700)}}$ and ${{\mathit \rho}{(2150)}}$ with the parameters of the ${{\mathit \rho}{(1450)}}$ and ${{\mathit \rho}{(1700)}}$ floating and the mass and width of the ${{\mathit \rho}{(2150)}}$ fixed at 2155 MeV and 320 MeV, respectively. The phases of the resonances are $\pi $, 0 and $\pi $, respectively.
