\caption{SAC fit parameters for the {[}Fe~{\scriptsize II}{]} narrow components.
$q$~(eV$^{-1}$) and $Y_{f}$ are fitting parameters. {${\overline{Y}}$
is $Y_{f}$ corrected for $q$ at a mean 3 eV excitation potential}.
$\log\overline{N}({\rm H})$ is the logarithm of the total number of Hydrogen
atom in the emitting volume.\label{TAB-fit_F}}
