\caption{Results for the SIS model for different lens samples and 
  $r_{\rm max}=150h^{-1}~{\rm kpc}$. $N_{\rm d}$,
  $N_{\rm s}$ and $N_{\rm p}$ are the numbers of lenses, sources and
  pairs in each measurement. Note that the number of sources can vary for
  different lens selections because not all source candidates are always lying
  within $r_{\rm max}$ of a lens. The best fit values of $\sigma_*$ and
  $\eta$ are given with 1-$\sigma$ error bars. The last two columns give the
  aperture mass within $150h^{-1}~{\rm kpc}$ and the corresponding
  mass-to-light ratio.}
