    There were major Subaru telescope failures tonight -- so we got zero new
    data.

    As you will see on the attached summary chart, our current best bets for
    HST include:
    071, 060, 065 -- likely options
    007, 081, 012 -- still in the game
    061 -- still being observed, if possible

    More info (like "light curve" info -- ie., going up or going down --
    final HST guide star info, -- ACS GRISM orient info., etc.)
    particularly on these candidates would be helpful before the final HST
    decisions have to be made 20 hours from now.

    Photo-z is listed in "completed" column as, for example, "z ~ 0.7"    If we have a real spectroscopic redshift estimate it is listed in the “galaxy z or [SN z]” column.   In the “complete” and “scheduled” columns  G=Gemini;  V=VLT;   K=Keck.

     

    [Info we thought we had from photo-z codes indicating, for 034,  z ~1.5,1.8 and elliptical and burst??  from Hyper z code went away, because they had the wrong host galaxy.

    maybe add SuF02-004, but this is probably a late supernova with light on ref, and brighter than reported on the tiles printout AND NO HST guide star.

    *= could be observed in the same ACS image (same FOCAS/Gemini slit?)  with the other candidate marked with a *

    **= could be observed in the same ACS image (same FOCAS/Gemini slit?) with the other candidate marked with a **

    [***]= could be observed in the same ACS image (same FOCAS/Gemini slit?) with the other candidate marked with a [***]

    _____  = still to do

    _____  = likely for HST

    _____  = still in the running for HST

    _____  = not as likely for HST

    _--__  = do not get spectroscopy:  either this has already been observed, or there is no HST guide star, or the photo-z is low.
