Estimated Total Execution Time (hours, including overheads)

• 29 hours

General Description

• This is a wide-field spectroscopy campaign targetting galaxies on the
   outskirts of a z=0.8 cluster and in a potentially associated larger scale structure
   detected in the X-ray.  The priorities of the pointings (Pointing 1 = 1, Pointing
   2 = 2, etc.) are set to provide the best chance of confirmation of the LSS.

Waiver Requests

• A waiver request for these fields was approved on 27 March:
  
  
  Subject: 081.A-0800B.02.WAV [APPROVED]
  Dear Olivia,
  
  I am glad to confirm that the requested waiver to have the OBs 1.5h long has been
   approved. Please note that the usual restriction applies that if the conditions
   degrade in violation of the constraints after the first hour the OB will not be
   repeated.
  
  Best regards,
  Marina Rejkuba

Critical Observing Condition Constraints

• Observations of this field can only be done within the standard +/- 2
   hours of culmination throughout April, May, and the first half of June.  As obtaining
   any scientific return from this programme requires observations being taken early
   in the semester, we have relaxed the constraints as much as we think possible to
   maximize our chances of obtaining data in this period.  
  
  If any further relaxation of the constraints could be made - e.g. observing to +/-
   3 hours of culmination, decreasing seeing or sky constrints, etc. - without jeopardizing
   our science goals (obtaining redshifts for I_AB > 24 galaxies by targetting spectral
   features around 7000 A), we would be happy to consider it and would very much appreciate
   any expert advice you could offer.  In two previous semesters, similar programmes
   conducted by our consortium in this field recieved no more than 6% of the requested
   exposure, so we are very keen to do anything possible to do better this time.

Time-Critical Aspects

• Observations of this field can only be done within the required +/- 2
   hours of culmination throughout April, May, and the first half of June.
