\caption{Constraints on dark matter halos of galaxies modelled by
  NFW profiles for different lens samples and 
  $r_{\rm max}=400h^{-1}~{\rm kpc}$. $N_{\rm d}$, $N_{\rm s}$ and
  $N_{\rm p}$ are the numbers of lenses, sources and pairs in each
  measurement. These numbers differ from those given in Table~\ref{tab:sis}
  because of the larger $r_{\rm max}$ used here. The virial radius
  $r_{\rm vir}^*$ and $\alpha$ are fitted quantities (see Fig.~\ref{fig:nfw}), the virial mass $M_{\rm vir}^*$ and the virial
  mass-to-light ratio $M_{\rm vir}^*/L^*$ are calculated from
      $r_{\rm vir}^*$. $\beta=3\alpha-1$ gives the scaling of
      $M_{\rm vir}/L$ with luminosity, $M_{\rm vir}/L\propto
      L^\beta$. All errors are 1-$\sigma$.}
