Zoom on the linear region of the SF for the four samples of AGN selected to investigate possible dependencies on M_BH (left column), λ_E (middle column), and L_bol (right column). The various panels show results for the main sample, MIR AGN, optically variable AGN, and Type I AGN (top to bottom lines). As in Fig. 8, in each panel we show the two subsets of sources delimited by the (logarithm of the) median value of the physical property of interest: red dots indicate the samples of sources with lower M_BH/λ_E/L_bol values and blue squares indicate the sources with higher values. The represented rest-frame baseline corresponds to ≈10−400 days.
