1  Taking into account both ${{\mathit \rho}{(1450)}}$ and ${{\mathit \rho}{(1700)}}$ contributions. Using the data of ACHASOV 2000I on ${{\mathit e}^{+}}$ ${{\mathit e}^{-}}$ $\rightarrow$ ${{\mathit \omega}}{{\mathit \pi}^{0}}$ and of EDWARDS 2000A on ${{\mathit \tau}^{-}}$ $\rightarrow$ ${{\mathit \omega}}{{\mathit \pi}^{-}}{{\mathit \nu}_{{\tau}}}$ . ${{\mathit \rho}{(1450)}}$ mass and width fixed at 1400 MeV and 500 MeV respectively.
2  Taking into account the ${{\mathit \rho}{(1700)}}$ contribution only. Using the data of ACHASOV 2000I on ${{\mathit e}^{+}}$ ${{\mathit e}^{-}}$ $\rightarrow$ ${{\mathit \omega}}{{\mathit \pi}^{0}}$ and of EDWARDS 2000A on ${{\mathit \tau}^{-}}$ $\rightarrow$ ${{\mathit \omega}}{{\mathit \pi}^{-}}{{\mathit \nu}_{{\tau}}}$ .
