$^{{a}}$ Equivalent width of \hb\  (\hbbc + \hbvbc)   and \feiiq in \AA\ $\pm $$2\sigma$ confidence level uncertainty. Note that those values have been computed on median spectra with flux normalized to unity at $\lambda = 5100$~\AA. Considering that the continuum shape is not flat, but that there is however little dispersion in continuum shape across the median spectra, it is $W$(\hb)~$\approx$~$I$(\hb)/1.1, and $W$(\feiiq)~$\approx I$(\feiiq)/1.25~\AA.
$^{{b}}$ {\it FWHM} of lines in the blend in units of~\kms\ computed by {\tt specfit} as for the individual sources.  Uncertainty is at $\pm $$2\sigma$ confidence level. See text for details.
$^{{c}}$~Intensity ratio of the \hbbc\ to total \hb\ line emission i.e., \hbbc\ and \hbvbc.
 $^{{d}}$~{\it FWHM} of the \hbbc\ component i.e., after removing \hbvbc.
 $^{{e}}$~Logarithm of \mbh, in solar masses, and of \lledd. Values have been computed following Paper II,  using the {\it FWHM}(\hbbc) reported in Col.~(6), and assuming the average bin luminsosity. Values are therefore only indicative. No \mbh\ or \lledd\ has been computed for median in spectral types since they are normalized median spectra made regardless of their luminosity.
 $^{{f}}$
  \feiiopt\ too faint for {\it FWHM} to be meaningfully constrained.
