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19  From an amplitude analysis of the ${{\mathit K}_S^0}$ ${{\mathit K}_S^0}$ system, superseded by LONGACRE 1986.
