There is a conspicuous signal for $f_0(1710) \to K^+K^-$ and a peak at higher mass which may be fitted with $f_2(2150) \to K\bar K$. From a combined analysis with $ωπ^+ π^-$ data, the branching ratio $BR(f_0(1710)\toππ)/BR(f_0(1710) \to K\bar K)$ is $< 0.11$ at the 95% confidence level.11 pages, 5 figures. Submitted to Phys. Lett.
