General Description

• This project is performing spectroscopy in the Blue for z~2 galaxies in
   the field of a candidate high redshift cluster. We use 2 MXU settings, each integrating
   for a total of 4 hours on target, split into 8 frames of 1800s and over 4 OBs (each
   long 1h+15m).
  
  OB namings and finding charts:

  In each of the masks, 3 square slits of 2x2" are cut, containing relatively bright
   stars that should be visible in the through-slit image, in order to allow an accurate
   centering of the MXUs. Two of these boxes are in the master-CCD (one near the top)
   and one box is in the slave-CCD (close to the bottom). 
  
  The main targets are generally faint in the B-band, but a few have B~23.5-24 and
   could be visible in the through slit image.

Waiver Requests

• Waiver request submitted on 18 March 2008, waiver ID 381.A-0567A.01, asking
   permission to use 1h15m long OBs. The request has been accepted on 25 March 2008

Critical Observing Condition Constraints

• We request dark nights and 0.8" seeing or better.
  
  We have constrained the airmass to be lower than 1.5. It is crucial for our observations
   to obtain high S/N at <4000A, in order to measure redshifts for z~2 galaxies,
   and thus observations at a low airmass are very important to obtain.

Time-Critical Aspects

• None

Special Execution Requirements

• We request that Mask1 OBs are executed first, as they have higher priority.
   We have assigned priorities to OBs accordingly.
