  Single target program : a QSO pair separated by 3.2" (and not 
resolved in the FC), whose components are aligned at PA=115 and have 
B magnitudes of 16.5 and 18.7. The given coordinates correspond to the 
brightest component, which is located at NW. For pointing, please try 
to follow suggestions given in README file by user.  

  The blue part of the spectrum has higher priority: this is why the 
blue slit-viewing CCD is selected. Should problems arise, please switch 
to RED camera on the fly. 

  Seeing <=0.8" is needed in order to separate well the spectra of the 
two components; however, this has to be intended as an average value 
over the exposure. Short jumps at higher values (<1.2 arcsec) are 
tolerable. THIN cirrus and some moon (possibly not in combination 
otherwise sky background is too bright) are also acceptable. Be aware 
that the 3 OBs using Dic1_346+564 have slightly tighter Airmass and FLI 
constraints. ThAr frames (to be taken in the BLUE arm only) are attached 
to each OB.
