1  From a fit to the cross section with contributions from ${{\mathit \omega}{(782)}}$, ${{\mathit \phi}{(1020)}}$, ${{\mathit \omega}{(1420)}}$, and ${{\mathit \omega}{(1650)}}$. An alternative fit which also includes ${{\mathit \phi}{(1680)}}$ gives $1649$ $\pm9$ MeV with a worse ${{\mathit \chi}^{2}}$. Supersedes ACHASOV 2024A.
2  From a fit to the cross section including contribution from ${{\mathit \omega}{(782)}}$, ${{\mathit \phi}{(1020)}}$, ${{\mathit \omega}{(1420)}}$, and ${{\mathit \omega}{(1650)}}$. Supersedes ACHASOV 2020A.
3  From a VDM fit to AKHMETSHIN 2017A ${{\mathit \omega}}{{\mathit \eta}}$ data with two additional resonances of low statistical evidences.
4  From a fit with contributions from ${{\mathit \omega}{(1420)}}$, ${{\mathit \omega}{(1650)}}$, and ${{\mathit \phi}{(1680)}}$. The mass of ${{\mathit \omega}{(1420)}}$ is fixed to the PDG 2018 value of 1420 MeV. Fixing also the width of ${{\mathit \omega}{(1420)}}$ to the PDG 2018 value of 220 MeV results in $1694$ $\pm9$ MeV measurement.
5  Could also be ${{\mathit \rho}{(1700)}}$. Branching ratio ${{\mathit J / \psi}}$ $\rightarrow$ ${{\mathit X}}{{\mathit \pi}^{0}}$ $\rightarrow$ ${{\mathit K}^{+}}{{\mathit K}^{-}}{{\mathit \pi}^{0}}$ = ($5.3$ $\pm0.3$ ${}^{+0.6}_{-0.5}$) $ \times 10^{-5}$.
6  From a fit of the interfering ${{\mathit \omega}{(1420)}}$ and ${{\mathit \omega}{(1650)}}$ with a relative phase of ${{\mathit \pi}}$ and other parameters floating.
7  From a fit with contributions from ${{\mathit \omega}{(1420)}}$, ${{\mathit \omega}{(1650)}}$, and ${{\mathit \phi}{(1680)}}$.
8  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.
9  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.
10  Using results of CORDIER 1981 and preliminary data of DOLINSKY 1991 and ANTONELLI 1992.
11  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.
12  Using data from BARKOV 1987, DOLINSKY 1991, and ANTONELLI 1992.
13  Using the data from ANTONELLI 1992.
14  Using the data from IVANOV 1981 and BISELLO 1988B.
15  Using the data from BISELLO 1991C.
16  From a fit to two Breit-Wigner functions and using the data of DOLINSKY 1991 and ANTONELLI 1992.
17  From the combined fit of the ${{\mathit \rho}}{{\mathit \pi}}$ and ${{\mathit \omega}}{{\mathit \pi}}{{\mathit \pi}}$ final states.
