${{\mathit n}}$2 ${{\mathit K}_S^0}$ 1  From partial wave analysis including all possible combinations of 0${}^{++}$, 2${}^{++}$, and 4${}^{++}$ resonances. 2  Spin 0 favored over spin 2. 3  In the SU(3) based model with a specific interference pattern of the ${{\mathit f}_{{{2}}}{(1270)}}$, ${{\mathit a}_{{{2}}}^{0}{(1320)}}$, and ${{\mathit f}_{{{2}}}^{\,'}{(1525)}}$ mesons incoherently added to the ${{\mathit f}_{{{0}}}{(1710)}}$ and non-resonant background. 4  $\mathit J{}^{P} = 0{}^{+}$, supersedes ARMSTRONG 1989D. 5  Systematic errors not estimated. 6  Decaying to ${{\mathit f}_{{{0}}}{(1370)}}{{\mathit \pi}}{{\mathit \pi}}$. 7  No $\mathit J{}^{PC}$ determination. 8  $\mathit J{}^{P} = 2{}^{+}$. 9  From a fit to the ${}^{}0{}^{+}$ partial wave. 10  No $\mathit J{}^{PC}$ determination. 11  ALDE 1992D combines all the GAMS-2000 data. 12  $\mathit J{}^{P} = 2{}^{+}$, ($0{}^{+}{}^{}$ excluded). 13  From an analysis ignoring interference with ${{\mathit f}_{{{2}}}^{\,'}{(1525)}}$. 14  From an analysis including interference with ${{\mathit f}_{{{2}}}^{\,'}{(1525)}}$. 15  Uses MRK3 data. From a partial-wave analysis of data using a K-matrix formalism with 5 poles, but assuming spin 2. Fit with constrained inelasticity. 16  No $\mathit J{}^{PC}$ determination. 17  $\mathit J{}^{P} = 2{}^{+}$ preferred. 18  From fit neglecting nearby ${{\mathit f}_{{{2}}}^{\,'}{(1525)}}$. Replaced by BLOOM 1983. 19  From an amplitude analysis of the ${{\mathit K}_S^0}$ ${{\mathit K}_S^0}$ system, superseded by LONGACRE 1986.
