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.
