1  From Dalitz plot analyses of ${{\mathit \eta}_{{{c}}}{(1S,2S)}}$ $\rightarrow$ ${{\mathit K}_S^0}$ ${{\mathit K}^{+}}{{\mathit \pi}^{-}}$ + c.c..
2  We take the central value of the two solutions and the larger error given.
3  S-matrix pole. Using ASTON 1988 and assuming ${{\mathit K}_{{{0}}}^{*}{(700)}}$, ${{\mathit K}_{{{0}}}^{*}{(1430)}}$.
4  T-matrix pole. Reanalysis of ASTON 1988 data.
