We restrict our analysis to a neighborhood of the resonance, using $\\pi\\pi$ data for the phase shift and inelasticity, and the invariant mass spectrum of the $J/\\psi\\to\\phi\\pi\\pi, \\phi K\\bar K$ decays. The formalism we use is based on unitarity and a generalized version of the Breit-Wigner parameterization. We find that a single pole describes the $f_0(980)$, the precise position depending upon the $\\pi\\pi$ data used. As a byproduct, v","authors_text":"A. Gallegos, G.
