Major Instrument Modes: FORS2 MOS

RA Range: 17:36

Constraint set (Typical seeing, Transparency,Airmass, FLI, Moon distance): 1.0 3THN 1.5 0.4 90.


Pre-imaging run? No! Chilean run? No! Special calibrations? Yes!
Time critical? No! ToO? No! Carry-over run? No!


Special Remarks:
Through-slit uses wider slit than science (1.2" vs 0.6").


 
 
MOS of faint stars in very crowded fields (bulge globular cluster).
Two MOS setups with two OBs each.

On July 22nd the user has submitted completely revised OBs based on
FORS pre-imaging. This will hopefully solved the problems caused earlier
by the using WFPC2 images to design the masks. The reference stars are
now much further out from the cluster center, thus making their
identification easier.

IMPORTANT: upon Hermann's suggestion, the through-slit image uses
a wider slit than the science (1.2" vs 0.6). Needless to say that
the daytime calibrations should be taken with the latter setup.
