1  Update of AKHMETSHIN 2000C.
2  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.
3  From the ${{\mathit \eta}}$ $\rightarrow$ ${{\mathit \gamma}}{{\mathit \gamma}}$ decay.
4  From the ${{\mathit \eta}}$ $\rightarrow$ 3 ${{\mathit \pi}^{0}}$ decay.
5  Observed by threshold-crossing technique. Mass resolution = 4.8 MeV FWHM.
6  From the ${{\mathit \rho}}−{{\mathit \omega}}$ interference in the ${{\mathit \pi}^{+}}{{\mathit \pi}^{-}}$ mass spectrum using the Breit-Wigner for the ${{\mathit \omega}}$ and leaving its mass and width as free parameters of the fit.
7  Systematic uncertainties underestimated.
8  From best-resolution sample of COYNE 1971 .
9  From ${{\mathit \omega}}-{{\mathit \rho}}$ interference in the ${{\mathit \pi}^{+}}{{\mathit \pi}^{-}}$ mass spectrum assuming ${{\mathit \omega}}$ width 12.6 MeV.
