  \caption{Intensities and full width at half maximum ({\it FWHM}) of the main 
  emission lines in the spectrum of LBQS~2212-1759; all intensities are in 
  units of ${\rm 10^{-16}~erg~cm^{-2}~s^{-1}}$ and have been corrected 
  for galactic extinction. Their uncertainties are typically 10\%. The {\it FWHM}
  are expressed in ${\rm km~s^{-1}}$ and have an uncertainty of 
  ${\rm \pm50~km~s^{-1}}$.}
