Fig. 4


IR emission from star-formation-heated cold dust, LSF, versus IR emission from AGN-powered dust, LAGN, for radio galaxies (filled red circles) and quasars (filled blue squares). Upper limits have been estimated as explained in the text. The large empty symbols correspond to the subsamples of FIR-detected RGs (circle) and QSRs (square), and non-detected RGs (triangle) and QSRs (diamond) discussed in Sect. 4.4. The dashed line marks LSF = LAGN.
