General Description

This is a new set of MXU masks (six) for the GOODS spectroscopic survey,
 specifically devoted to SPITZER/MIPS sources.
There are 36.0 hrs of observations (incl.overheads). Each mask is exposed for ~6hrs
 (6 OBs). Offsets are specified to have a 3 point dithering pattern, with ~1 pixel
 shift between OBs. Most of the objects are very faint, so almost all of them will
 not be visible even in the through-slit exposure. To deal with this, 4 to 6 stars
 have been put in narrow slits, for each mask,  which have been marked with green
 circles in the associated finding charts. These stars should be visible in the slits
 in the 0 offset position.
