Special Execution Requirements

• There are two OBs per object (quasar). In order for our search for MgII
   absorption lines to be complete, we need to have 
  both OBs executed for each object. So please complete the OBs relative to the same
   object before switching to a new one. 
  This will allow a full coverage of the quasar spectrum.
  In addition, executing the OBs relative to the same object in sequence would save
   the overhead time needed to point the 
  telescope toward a new direction. Since some of the exposure times are short, this
   would make a substantial difference 
  in the fraction of time spent in "science" mode.
  
  Finally, we have submitted one OB for observing a standard star for telluric calibration
   (DbaseID: 212087). We would 
  like to have this OB executed right after (or before) the quasar 3C 208 (DbaseID's:
   209234, 209236). This should 
  provide us an accurate determination of the telluric features for this object. For
   most objects, we will have to rely 
  on a less accurate procedure, based on data for telluric standard taken at different
   time and in different directions 
  in the sky. However, comparing the results from the two procedures for quasar 3C
   208 will allow us to determine the 
  accuracy of the overall subtraction of the telluric features.
