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
Gabriele

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%
S02-062 13:22:32.9 +27:43:21.6 3 24.28 4.29 121%

S02-072 SDF2 13:24:40.8 +27:22:15.5 3 24.32 0.00 0 (very
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:
C02-029 comix 23.1 15.29 15% weird lightcurve
