Top panel: same as the top-right panel of Fig. 9, with only the SSs and SIMSs of the 2002−2003 outburst (dark red circles, with SIMS highlighted by a thicker black contour) and its HIMSs (grey squares). Lines of approximately constant D_F are shown with dashed lines, and the related values are shown in the figure. Bottom panel: same as the bottom left panel of Fig. 9, but with again the SS-SIMS (dark red dashed, with SIMS only highlighted by the dot-dashed line) and HIMS (grey) of the 2002−2003 outburst, plus the 44 radio-loud AGNs excluded from our AGN sample (black dotted line).
