        We're working on all of this here.

        Fine. Although, whatever we find about Nessie shouldn't alter our
    considerations much. We're not going to get much out of it with a couple
    of z-band points. Grism might be useful for IDing it at least. But it's
    gotta be pretty old by now.

        Anyway, back to work.
