1  Statistical error negligible.
2  From a single-pole fit.
3  In the ${{\mathit f}_{{{0}}}{(980)}}{{\mathit \pi}}$ wave.
4  In the ${{\mathit f}_{{{0}}}{(500)}}{{\mathit \pi}}$ wave.
5  From a fit to $\mathit J{}^{PC} = 0{}^{-+}{{\mathit f}_{{{0}}}{(980)}}{{\mathit \pi}}$, ${{\mathit f}_{{{0}}}{(1370)}}{{\mathit \pi}}$ waves.
6  From a fit to $\mathit J{}^{PC} = 0{}^{-+}{{\mathit K}_{{{0}}}^{*}{(1430)}}{{\mathit K}^{-}}$ and ${{\mathit f}_{{{0}}}{(980)}}{{\mathit \pi}^{-}}$ waves.
