General Description

Multi-slit (MXU) spectroscopy of galaxies in an extended super galaxy
 group (about 10'x16' on the sky) made of four individual galaxy groups at z~0.37.
  The masks are designed in pairs, e.g. m1a and m1b, where several galaxies are in
 common to obtain high S/N spectra for measuring kinematics.  The finding charts
 for each mask pair (e.g. 082.B-0765B.m1ab) show the acquisitions stars (shown with
 squares) for each pair of masks while the finding chart for each mask (e.g. 082.B-0765B.m1a-mask)
 includes the mask design overlaid on the image.  There are no offsets along the
 slit in the science templates because the masks include tilted slits.
Many of the targeted galaxies are bright enough that they should be visible in the
 through-slit image.
A waiver has been granted for the 1.3 hour OBs.
The VIMOS astrometry was corrected before using the mosaic to design the masks and
 finding charts; the astrometry should be excellent.
