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.
