\caption{Narrow emission lines. The Equivalent Width ({\it EW}) as measured  with the LETGS, except for the \ion{Mg}{xi}, \ion{Al}{xiii} and \ion{Si}{xiii}~forbidden lines (MEG), and flux are listed. In the last column the ionization parameter, $\xi$, where the ion has the highest column density is given. Forbidden lines are indicated by~f, intercombination lines by~i. Below the line the \ion{C}{v} and \ion{O}{vii}~RRC are listed. The rest wavelengths are taken from Drake (\cite{drake}).}\label{tab:nel}
