\caption{The best fit column densities using model B for the ions for which the outflow velocity and velocity broadening are well constrained. The outflow velocity~$v$ and the rms~velocity broadening $\sigma$ are listed as well as the ionization parameters~$\xi$ and~$U$ for which the ion has its maximum column density. The column densities are from the fit including the broad emission lines (Sect.~\ref{sect:bel}).}
