This is a program to obtain wide field imaging around a set of high redshift
clusters. The goal is to obtain 1h in I, 2h in R, and 1h in V to
look for structures surrounding the clusters which could be associated with
the clusters.  The major observing constraints are that program needs to be
able to distinguish z=0.5-0.9 galaxies from stars, so need seeing better than
1.2", the typical size of giant ellipticals for these clusters.  The R-band is
requested at better than 1.0".

  ! Critical Observing Condition:
Observe the R-band OB's with as small a PSF as possible.

This program is allowed to use OBs longer than 1h.

As twilight and dome flats don't work very well for the WFI (and any other
30' FOV camera), please try to arrange to take multiple OB's of the same
passband on different fields on any given night, to allow the best nightsky
flats.  In particular, all 4 V-band OB's need to be taken on the same night
if possible.  Also, please try to take the I-band data in this program on the
same night as those of 69.A-9009(A) in order to allow for a better
flat field and fringe correction on both sets of data.
