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 ${{\mathit \omega}{(1650)}}$. See ACHASOV 2020A for a further analysis of the ${{\mathit \pi}^{+}}{{\mathit \pi}^{-}}{{\mathit \pi}^{0}}$ data.
3  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.
4  Using results of CORDIER 1981 and preliminary data of DOLINSKY 1991 and ANTONELLI 1992 .
5  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.
6  Using data from BARKOV 1987 , DOLINSKY 1991 , and ANTONELLI 1992 .
7  Using the data from ANTONELLI 1992 .
8  Using the data from IVANOV 1981 and BISELLO 1988B.
9  From a fit to two Breit-Wigner functions and using the data of DOLINSKY 1991 and ANTONELLI 1992 .
10  From a fit to two Breit-Wigner functions interfering between them and with the $\omega ,\phi $ tails with fixed ($+,–,+$) phases.
