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 a fit of the pion form factor in the energy range 0.32 $<$ $\sqrt {s }$ $<$ 1.2 GeV using the GOUNARIS 1968 parametrization with the complex phase of the ${{\mathit \rho}}−{{\mathit \omega}}$ interference leaving ${{\mathit \rho}{(1450)}}$, ${{\mathit \rho}{(1700)}}$ resonances as free parameters of the fit. Systematic errors not estimated.
7  The values were extracted from a dispersively improved Breit-Wigner parameterization and do not include vacuum polarization. Inclusion of vacuum polarization gives $782.736$ $\pm0.024$ MeV.
8  The ${{\mathit \omega}}$ mass was extracted from a dispersively improved Breit-Wigner parameterization, the ${{\mathit \omega}}$ width fixed at $8.49$ $\pm0.08$ MeV. The value does not include vacuum polarization which would shift the mass to $781.81$ $\pm0.09$ $\pm0.03$ MeV. The mixing parameter is assumed real valued.
9  The values were extracted from a dispersively improved Breit-Wigner parameterization and do not include vacuum polarization.
10  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.
11  Systematic uncertainties underestimated.
12  Systematic uncertainties not estimated.
13  From best-resolution sample of COYNE 1971.
14  From ${{\mathit \omega}}-{{\mathit \rho}}$ interference in the ${{\mathit \pi}^{+}}{{\mathit \pi}^{-}}$ mass spectrum assuming ${{\mathit \omega}}$ width 12.6 MeV.
