The second part of the statement in Proposition 9 of the original publication was incorrect. It should read as follows: (ii) If ξ(t) = (ξ ^u(t), ξ^s (t))^T is a fixed point of T_x^s for some x^s ∈ R^ds and ║ξ║_∞ ≤ r^*, where r^* satisfies (12), then ξ(t) is a solution of (8) with ξ^s(0) = x^s and lim_t→∞ ξ(t) = 0.
