    Hmm... that's surprising, Bahram. I'll attach an image showing the
    neighborhood of this host galaxy (with a circle on the host galaxy).
    It looks like there is a clear galaxy right at the coordinates we
    sent. Is it easy for you to tell if this matches something in your
    catalog (and if not, why not)?
