1  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 width $\Gamma ({{\mathit K}_{{0}}^{*}{(1430)}}$) = 210 MeV.
2  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.
3  From the isobar model with a complex pole for the ${{\mathit \kappa}}$.
4  From a non-parametric analysis.
5  A Breit-Wigner mass and width.
6  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.
7  S-matrix pole. Using ASTON 1988 and assuming ${{\mathit K}_{{0}}^{*}{(700)}}$, ${{\mathit K}_{{0}}^{*}{(1950)}}$.
8  Using ASTON 1988 and assuming ${{\mathit K}_{{0}}^{*}{(700)}}$.
9  T-matrix pole. Reanalysis of ASTON 1988 data.
10  Breit-Wigner fit. Using ASTON 1988 .
11  Assuming a low-mass scalar ${{\mathit K}}{{\mathit \pi}}$ resonance, ${{\mathit \kappa}{(700)}}$.
12  T-matrix pole. Using data from ESTABROOKS 1978 and ASTON 1988 .
13  $\mathit J{}^{P}$ not determined, could be ${{\mathit K}_{{2}}^{*}{(1430)}}$.
14  T-matrix pole.
15  Uses a model for the background, without this background they get a mass 1340 MeV, where the phase shift passes 90$^\circ{}$.
16  Mass defined by pole position. From elastic ${{\mathit K}}{{\mathit \pi}}$ partial-wave analysis.
