Fig. 9


Distribution of the thermal emission flag for all the FSRQs with good or excellent optical data flag (see text for details). Black solid histograms: radio sample; red dashed histograms: Fermi-LAT sample; green dot-dashed histograms: Swift BAT sample; and blue dotted histograms: RASS sample. As the X-ray emission of all BL Lacs was not contaminated, the BL Lac data are not plotted here.
