1  Averaged over six nuclear targets, no statistically significant dependence on target nucleus observed.
2  Breit-Wigner mass.
3  T-matrix pole.
4  Mass errors enlarged by us to $\Gamma /\sqrt {\mathit N }$; see the note with the ${{\mathit K}^{*}{(892)}}$ mass.
5  From a partial-wave analysis of data using a K-matrix formalism with 5 poles.
6  From an energy-independent partial-wave analysis.
7  From an amplitude analysis of the reaction ${{\mathit \pi}^{+}}$ ${{\mathit \pi}^{-}}$ $\rightarrow$ 2 ${{\mathit \pi}^{0}}$ .
8  From an amplitude analysis of ${{\mathit \pi}^{+}}$ ${{\mathit \pi}^{-}}$ $\rightarrow$ ${{\mathit \pi}^{+}}{{\mathit \pi}^{-}}$ scattering data.
9  Using CLEO-c data but not authored by the CLEO Collaboration.
10  From a fit to a Breit-Wigner line shape with fixed $\Gamma $ = 185 MeV.
11  4-poles, 5-channel K matrix fit.
12  From analysis of L3 data at 91 and $183 - 209$ GeV.
