  We show that resonant states in scattering on asymptotically hyperbolic
man-ifolds that are analytic near conformal infinity, have analytic radiation
patterns at infinity. On even asymptotically hyperbolic manifolds we also show
that smooth solutions of Vasy operators with analytic coefficients are also
analytic. That answer a question of M.Zworski ([14] Conjecture 2). The proof is
based on previous results of Baouendi-Goulaouic and Bolley-Camus-Hanouzet and
for convenience of the reader we present an outline of the proof of the latter.
