The employed Faddeev approach requires as main input amplitudes for the two-body subsystems $\\bar KN \\to \\bar KN$ and $\\bar KN \\to \\pi\\Sigma$. For the latter results from recently published chiral unitary models of the $\\bar KN$ interaction are utilized. The $\\bar KN \\to \\bar KN$ amplitude itself, however, is taken from a recent partial-wave analysis.
