Estimated Total Execution Time (hours, including overheads)

• 1h19m27s per OB

General Description

• Target is a FAINT (K~20), BIG (~2.5") high z galaxy, which we observe
   at 4 different positions in the 8x8" FOV (--> hence no need for sky positions).
   The offset star (H=16.9) must be ACCURATELY CENTERED in the fov because the galaxies
   are so big (subtract sky frame first if necessary). Continuum might be visible after
   subtracting two frames and median collapsing, but do NOT worry if no continuum is
   seen. 
  The observing sequence starts with observing the offset star at the first two positions
   (AB) where the target will be observed, then observing the target at 4 different
   positions (ABCD) and then observing the offset star again at the last two positions
   (CD). Rationale is that based on extensive visitor mode experience we have noticed
   that the target can move significantly on the chip (depending on parallactic angle,
   elevation etc). We correct for this using the star observations during the data
   reduction.
  
  Two finding charts have been attached. The first ("fc_big_UDF2.jpg") shows a large
   area  with the target and offset star. The second ("fc_small_UDF2.jpg") shows the
   8x8 arcsecond fov at the different offset positions on the science target (red-magenta-blue-green
   squares).
  
  Note the large distance between offset star and target: 63".
  
  "Verify" gives a warning that the target moves outside the FOV. IGNORE this warning
   (the target is in the FOV, it the OB structure (first observing a psf star &
   not using the blind offset option) that causes this error.
