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  The values were extracted from a dispersively improved Breit-Wigner parameterization and do not include vacuum polarization. Inclusion of vacuum polarization gives $8.63$ $\pm0.05$ MeV.
4  The values were extracted from a dispersively improved Breit-Wigner parameterization and do not include vacuum polarization.
5  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.
6  Systematic uncertainties underestimated.
7  Relativistic Breit-Wigner includes radiative corrections. Systematic uncertainties not estimated.
8  Systematic uncertainties not estimated.
9  Observed by threshold-crossing technique. Mass resolution = 4.8 MeV FWHM.
