Fig. A.1


Rest-frame optical spectra of 8 out 28 AGNs for which we derive density-sensitive flux ratios. For each object, we show the spectrum (black curve) and the best-fit models (red curves) obtained from multicomponent simultaneous fit in the regions around the Hβ and the Hα emission. The dashed vertical lines mark the location of Hβ, [O III] doublet, [O I], Hα, [N II] and [S II] doublets. Best-fit NC and BC profiles are shown with green curves; blue curves show OC emission.
