1  From partial wave analysis including all possible combinations of 0${}^{++}$, 2${}^{++}$, and 4${}^{++}$ resonances.
2  Supersedes ACCIARRI 1995J.
3  From an analysis including interference with ${{\mathit f}_{{0}}{(1710)}}$.
4  From a fit to a Breit-Wigner line shape plus a second-order polynomial function. Systematic errors not evaluated.
5  From analysis of L3 data at 91 and $183 - 209$ GeV.
6  From an analysis ignoring interference with ${{\mathit f}_{{0}}{(1710)}}$.
