Abstract: The $f_0$ mesons are studied in a combined analysis of data on isoscalarS-wave processes $\pi\pi\to\pi\pi,K\overline{K},\eta\eta$ and on decays$J/\psi\to\phi(\pi\pi, K\overline{K})$, $\psi(2S)\to J/\psi(\pi\pi)$and $\Upsilon(2S)\to\Upsilon(1S)\pi\pi$ from the Argus, Crystal Ball,CLEO, CUSB, DM2, Mark~II, Mark~III, and BESIII Collaborations. Themethod of analysis, based on analyticity and unitarity and usingan uniformization procedure, is set forth with some details. Somespectroscopic implications from results of the analysis are discussed.T = The scalar mesons in multi-channel $\pi\pi$ scattering and decays of the $\psi$ and $\Upsilon$ families
