Fig. 3
Radio-loudness distribution for each spectral kind as classified by the [NII]-based diagram. SFGs are in blue, composites in purple, Seyferts in green and LINERs in red. In each panel, sources to the left of the dashed line (log R = 2.4) are radio quiet, while sources to the right are radio loud (Panessa et al. 2007). The overall Effelsberg sample is shown in gray.
