General Description

• VIMOS MOS LR-blue spectroscopy of sum-mm selected galaxies in the chandra
   deep field south discovered from our APEX/LABOCA survey.  The masks also contain
   radio, Spitzer 70um selected and UV-selected star-forming galaxies.  Our aim is
   to derive spectroscopic redshifts for these z~2--3 galaxies.
  
  Each OB contains 3x1200second exposures (dithered along the slit by +/-1").  We
   have a waiver to allow these slightly longer exposure times.
  
  *** IMPORTANT ***
  
  Please note that there are OBs that re-use ADP files for specific quadrants.  For
   example, we have designed masks for each quadrant but in some cases we have re-designed
   an ADP for a single quadrant where we wanted spectroscopy of a galaxy that could
   not be accomodated is the first ADP.  This can be seen from the nomenclature of
   the OB Name.
  
  for example:
  MOS zLESS "Point 1a" and "Point 1b" have the same mask ADP in quadrant 4, but different
   mask ADPs for Q1, Q2 and Q3.  Hence the names: "Point 1a 1111" and "Point 1b 2221".
   In other words, when doing the "Point 1b" observation, the mask for Quadrant 4 is
   the same as "Pointing 1a", BUT the masks for Quadrants 1, 2 and 3 are different.
   
  
  Likewise, for Pointing 2a and Pointing 2b have the same mask ADP for Q1, Q2, Q4,
   but a different mask ADP for Q3.  Hence these are labelled "Point 2a 1111" and "Point
   2b 1121"
  
  "Point 3a" and "Point 3b" have the same mask ADPs for Q2, Q3 and Q4 but a different
   mask for Q1.
  
  "Point 4" has the same masks for all observations.
  
  We have done this becuase in some quadrants we have redesigned masks to accomodate
   a specific galaxy - but did not need to redesign the entire VIMOS mask for all quadrants.

Waiver Requests

• A waiver was requested to allow the OBs to be 1h33mins (rather than the
   standard 1h05m) so that we could execute 3x1200 second exposures.  this was accepted
   on 19 Aug 2009.
