1  From a phenomenological model based on vector meson dominance with interfering ${{\mathit \rho}{(770)}}$, ${{\mathit \rho}{(1450)}}$, and ${{\mathit \rho}{(1700)}}$. The ${{\mathit \rho}{(1700)}}$ mass and width are fixed at 1720 MeV and 250 MeV, respectively. Systematic uncertainties not estimated. Supersedes ACHASOV 2013 .
2  Using Breit-Wigner parameterization of the ${{\mathit \rho}{(1450)}}$ and assuming equal probabilities of the ${{\mathit \rho}{(1450)}}$ $\rightarrow$ ${{\mathit \pi}}{{\mathit \pi}}$ and ${{\mathit \rho}{(1450)}}$ $\rightarrow$ ${{\mathit \omega}}{{\mathit \pi}}$ decays.
3  Using the data of AKHMETSHIN 2003B and BISELLO 1991B assuming the ${{\mathit \omega}}{{\mathit \pi}^{0}}$ and ${{\mathit \pi}^{+}}{{\mathit \pi}^{-}}$ mass dependence of the total width. ${{\mathit \rho}{(1700)}}$ mass and width fixed at 1700 MeV and 240 MeV, respectively.
4  Using Breit-Wigner parameterization of the ${{\mathit \rho}{(1450)}}$ and assuming the ${{\mathit \omega}}{{\mathit \pi}^{-}}$ mass dependence for the total width.
5  Mass-independent width parameterization. ${{\mathit \rho}{(1700)}}$ mass and width fixed at 1700 MeV and 235 MeV respectively.
6  Using data from BISELLO 1991B, DOLINSKY 1986 and ALBRECHT 1987L.
7  Not separated from ${{\mathit b}_{{1}}{(1235)}}$, not pure $\mathit J{}^{P} = 1{}^{-}$ effect.
