1  From Dalitz plot analyses of ${{\mathit \eta}_{{{c}}}{(1S,2S)}}$ $\rightarrow$ ${{\mathit K}_S^0}$ ${{\mathit K}^{+}}{{\mathit \pi}^{-}}$ + c.c..
2  Using both ${{\mathit \eta}}$ $\rightarrow$ ${{\mathit \gamma}}{{\mathit \gamma}}$ and ${{\mathit \eta}}$ $\rightarrow$ ${{\mathit \pi}^{+}}{{\mathit \pi}^{-}}{{\mathit \pi}^{0}}$. From a likelihood scan in the presence of several interfering scalar-meson resonances with fixed mass $\mathit M({{\mathit K}_{{{0}}}^{*}{(1430)}}$) = 1435 MeV.
3  S-Matrix pole. Supersedes BUGG 2006. Combined analysis of ASTON 1988, ABLIKIM 2006C, AITALA 2006, and LINK 2009 using an s-dependent width with couplings to ${{\mathit K}}{{\mathit \pi}}$ and ${{\mathit K}}{{\mathit \eta}^{\,'}}$, and the Adler zero near thresholds.
4  From the isobar model with a complex pole for the ${{\mathit \kappa}}$.
5  From a non-parametric analysis.
6  A Breit-Wigner mass and width.
7  S-matrix pole. Reanalysis of ASTON 1988, AITALA 2002, and ABLIKIM 2006C including the $\kappa $ with an $\mathit s$-dependent width and an Adler zero near threshold.
8  S-matrix pole. Using ASTON 1988 and assuming ${{\mathit K}_{{{0}}}^{*}{(700)}}$, ${{\mathit K}_{{{0}}}^{*}{(1950)}}$.
9  Using ASTON 1988 and assuming ${{\mathit K}_{{{0}}}^{*}{(700)}}$.
10  T-matrix pole. Reanalysis of ASTON 1988 data.
11  Breit-Wigner fit. Using ASTON 1988.
12  Assuming a low-mass scalar ${{\mathit K}}{{\mathit \pi}}$ resonance, ${{\mathit \kappa}{(700)}}$.
13  T-matrix pole. Using data from ESTABROOKS 1978 and ASTON 1988.
14  $\mathit J{}^{P}$ not determined, could be ${{\mathit K}_{{{2}}}^{*}{(1430)}}$.
15  T-matrix pole.
16  From elastic ${{\mathit K}}{{\mathit \pi}}$ partial-wave analysis.
