Erratum: ``Maximal Chains in ${}^\omega\omega$ and Ultrapowers of the Integers''

This note is intended as a supplement and clarification to the proof of Theorem 3.3 of [ShSr:465]; namely, it is consistent that b = aleph_1 yet for every ultrafilter U on omega there is a <=^* chain {f_xi : xi in omega_2} such that {f_xi /U: xi in omega_2} is cofinal in omega /U .
