1  Seen in ${{\mathit \psi}{(2S)}}$ decay with branching ratio ${{\mathit \psi}{(2S)}}$ $\rightarrow$ ${{\mathit K}^{\pm}}{{\mathit X}}$ $\rightarrow$ ${{\mathit K}^{+}}{{\mathit K}^{-}}{{\mathit \eta}}$ = ($2.0$ $\pm0.4$ ${}^{+1.9}_{-0.4}$) $ \times 10^{-6}$.
2  From energy-independent partial-wave analysis.
3  From a fit to $\mathit Y{}^{2}_{6}$ moment. $\mathit J{}^{P} = 3{}^{-}$ found.
4  From a partial wave amplitude analysis.
5  From a fit to $\mathit Y{}^{0}_{6}$ moment.
6  Errors enlarged by us to 4${}\Gamma /\sqrt {\mathit N }$; see the note with the ${{\mathit K}^{*}{(892)}}$ mass.
7  ESTABROOKS 1978 find that BRANDENBURG 1976D data are consistent with 175 MeV width. Not averaged.
