    Hi Rachel,

    you might be right. However, in Bahram's reply to Greg's question
    about the 076 host galaxy type he only discussed photo-z method
    based on ACS/near-IR (ground) image data. He never mentioned
    ACS grism spectra nor WFPC2 UV images. This makes me
    suspicios that he only used the familiar GOODs surveys data and
    did not actually account for anything else. This is not a reason
    to blame him of course. He did an excellent, urgent, and crucial job.
    My point is that *we* may want to know more about our precious
    candidate and its host.
