Hi,
I tend to agree with both Chris and Isobel about the high risk
of trying to do both targets at NIRI under the current conditions. It
seems to me that it would be sensible to go for the brighter z=1.08
target, S02-032, with ISAAC tonight and tomorrow.
The 2 x z=0.5 guys for which we also got ISAAC time should be left
for the May run, where we should be able to make better optical
lightcurves.
