1  From a fit of the interfering ${{\mathit \omega}{(1420)}}$ and ${{\mathit \omega}{(1650)}}$ with a relative phase of ${{\mathit \pi}}$ and other parameters floating.
2  From a fit with contributions from ${{\mathit \omega}{(782)}}$, ${{\mathit \phi}{(1020)}}$, ${{\mathit \omega}{(1420)}}$, and ${{\mathit \omega}{(1650)}}$.
3  From a fit of a VMD model with two effective resonances with masses of 1450 MeV and 1700 MeV to describe the excited vector states ${{\mathit \omega}{(1420)}}$, ${{\mathit \rho}{(1450)}}$, ${{\mathit \omega}{(1650)}}$, and ${{\mathit \rho}{(1700)}}$. Systematic errors not evaluated.
4  From the combined fit of ANTONELLI 1992 , ACHASOV 2001E, ACHASOV 2002E, and ACHASOV 2003D data on the ${{\mathit \pi}^{+}}{{\mathit \pi}^{-}}{{\mathit \pi}^{0}}$ and ANTONELLI 1992 on the ${{\mathit \omega}}{{\mathit \pi}^{+}}{{\mathit \pi}^{-}}$ final states. Supersedes ACHASOV 1999E and ACHASOV 2002E.
5  Using results of CORDIER 1981 and preliminary data of DOLINSKY 1991 and ANTONELLI 1992 .
6  Using the data of AKHMETSHIN 2000D and ANTONELLI 1992 . The ${{\mathit \rho}}{{\mathit \pi}}$ dominance for the energy dependence of the ${{\mathit \omega}{(1420)}}$ and ${{\mathit \omega}{(1650)}}$ width assumed.
7  From a fit to two Breit-Wigner functions and using the data of DOLINSKY 1991 and ANTONELLI 1992 .
8  From a fit to two Breit-Wigner functions interfering between them and with the $\omega ,\phi$ tails with fixed ($+,–,+$) phases.
