Major Instrument Modes: WFI with VRI filters

RA Range: 10.6h - 12.6h

Constraint set (Typical seeing, Transparency,Airmass, FLI, Moon distance): 1.2 2CLR 2.0 0.,0.8 30


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


Special Remarks:


 
 
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 requested for both twilight and dome flats to produce the
best nightsky flats.
This program is allowed to use OBs longer than 1h.
