General Description

• FLAMES IFU OBSERVATIONS OF LYMAN-ALPHA BLOBS IN SA22
  ----------------------------------------------------
  
  Targets are large emission-line nebulae (Lyman-alpha Blobs, LABs) in the SA22 structure
   at z=3.1, selected from a narrow-band survey of the field (Matsuda et al. 2004).
   Surface brightness of targets is in the range 26-27 mag/asec^2.
  
  
  SPECIAL EXECUTION REQUIREMENTS:
  
  In five of the OBs we have included night-time flat-fields.  We have
  interspersed these flats throughout the observations and therefore request
  that the OBs are executed in database ID order.  This should ensure we
  pick up any temporal variation in the fiber-to-fiber response, and
  therefore get the best out of the data-reduction/sky-subtraction.
  
  (We have assigned priorities to the OBs to ensure that these flat-fields
  will be interspersed throughout the run.  Each priority block contains six
  OBs.  Five of these OBs contain ~2700s integrations on the science target,
  the sixth OB contains a ~2300s integtation + 1 night-time flatfield).
