Well, we really know how to make the last nights before the HST deadline
exciting, don't we! Zero time tonight with the dome open here in
Hawaii, at either the Keck or Gemini. So this is going to go down to
the wire (and that's if we're lucky).
For those of you who didn't follow the email with Isobel, we have been
trying to observe simultaneously at Keck and Gemini for the last two
nights and for tomorrow night. After that, Gemini has one more night on
its own before the HST deadline. Meanwhile, Chris has requested
permission for us to put more of our FORS2 time into FORS1 time so that
we can continue to try to observe at VLT right up to the HST deadline,
too (after which we will go back to FORS2 queue time, and perhaps finish
up spectra on whatever we still haven't observed particulary for the
CFHT rolling search candidates). The attached planning list is
therefore broken up into what we think we can observe at each telescope
(although of course we may end up trading these observations around).
The one hopeful element at the moment is that Chris reported seeing
emission lines for both the candidates he observed, C02-030/Troudux and
T02-015, that could place both of them around z ~ 0.8. However, we
haven't yet heard from Gabriele and Chris if they see any evidence for
supernovae in either of these candidates' spectra.
That system of clouds that has been sitting over us presumably has to
leave someday! It would just be nice if it did so very, very soon.
Goodnight/goodmorning.

Unassigned Candidates
=====================
These are all LBL magnitudes, so I'm not sure how much (0.5mag or more) to
subtract off these values:
S02-066 Ugluk 3 26.12LBL 5.59 16%
S02-069 2 25.43LBL 9.23 24% (unvetted)
S02-081 2 25.65LBL 7.65 30% (unvetted)
S02-065 Wormtongue 3 25.68LBL 8.31 10% "suspect"
The Bottom Of the Barrel
==========================
These first one is important to rule out or rule in because it is
in CFHT field (visible from VLT/ISAAC) and could be deep (especially the first
one):
C02-023 14:00:39.1 +04:52:20.1 3 23.9 7.32 28% (yuckish)
S02-063 13:25:32.5 +27:22:14.0 3 26.13LBL 5.21 53% YUCK [not
that bad?]

Currently candidates that are considered not worth spectrum:
