LDSS 3 imaging (January 2008)

   g-band
      t_exp = 1.67 hrs
      seeing measured from image = 1.0"
      zero point = 27.5 +/- 0.1  (AB magnitudes)
      WCS information in header
      galaxy at x,y = 1015,1360, RA,Dec = 10:44:32.936, -01:25:03.49
      
   i-band
      t_exp = 0.33 hrs
      No WCS information, but registered to g-band image
      QSO at x,y = 1021,1351

   Notes: 

   The galaxy is essentially unresolved along the minor axis, but
   marginally resolved along the major axis.  The observed FWHM along
   the major axis is 1.64", and the FWHM measured for point sources is
   1.02" in this direction.  This gives a deconvolved FWHM of ~1.3",
   or ~11 kpc for H0=71, Omega_m=0.27.

   g-band magnitude of the galaxy is 23.8 +/- 0.2

   Separation between the QSO and galaxy is roughly 1.95" (center to
   center), or ~16 kpc.

LRIS spectrum (March 2008 & May 2008)

   total exposure time = 3000 sec

   The spectrum combines the blue and red arms, and has been converted
   to erg/s/cm2/Ang using the g-band photometry.
