1  Seen in ${{\mathit \psi}{(2S)}}$ decay with branching ratio ${{\mathit \psi}{(2S)}}$ $\rightarrow$ ${{\mathit X}}{{\mathit \eta}}$ $\rightarrow$ ${{\mathit K}^{+}}{{\mathit K}^{-}}{{\mathit \eta}}$ = ($1.9$ $\pm0.4$ ${}^{+0.5}_{-1.3}$) $ \times 10^{-6}$.
2  See however KLOET 1996 who fit ${{\mathit \pi}^{+}}{{\mathit \pi}^{-}}$ only and find waves only up to $\mathit J = 3$ to be important but not significantly resonant.
3  $\mathit I(\mathit J{}^{P}) = 1(3{}^{-})$ from simultaneous analysis of ${{\mathit p}}$ ${{\overline{\mathit p}}}$ $\rightarrow$ ${{\mathit \pi}^{-}}{{\mathit \pi}^{+}}$ and ${{\mathit \pi}^{0}}{{\mathit \pi}^{0}}$.
4  $\mathit I = 0$, $1{}^{}{}^{}$. $\mathit J{}^{P} = 3{}^{-}$ from Barrelet-zero analysis.
5  $\mathit I(\mathit J{}^{P}) = 1(3{}^{-})$ from amplitude analysis.
