    Bad luck!

    I'm getting the data now but without calibrations for the moment.
    I'll do my best with what I have and I'll let you know as soon as I have
    something to show.
    Cheers

    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?]

    S02-068 Bilbo 13:25:42.7 +27:21:09.9 2 26.20 4.88 38%
    S02-056 13:22:16.4 +27:44:45.3 3 26.0LBL 4.91 1198%

    weak)
    S02-073 SDF3 13:24:41.5 +27:24:56.7 3 23.75 0.00 0 (very
    weak)

    Currently candidates that are considered not worth spectrum:
