1  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.
2  Using the data of AKHMETSHIN 2001B on ${{\mathit e}^{+}}$ ${{\mathit e}^{-}}$ $\rightarrow$ ${{\mathit \eta}}{{\mathit \gamma}}$ , AKHMETSHIN 2000D and ANTONELLI 1988 on ${{\mathit e}^{+}}$ ${{\mathit e}^{-}}$ $\rightarrow$ ${{\mathit \eta}}{{\mathit \pi}^{+}}{{\mathit \pi}^{-}}$ .
3  Using the data of ANTONELLI 1988 , DOLINSKY 1991 , and AKHMETSHIN 2000D. The energy-independent width of the ${{\mathit \rho}{(1450)}}$ and ${{\mathit \rho}{(1700)}}$ mesons assumed.
