SFR versus M_star (top panel) and f_abs versus L_bol (bottom panel) for the early-type (E/S0 and LBS) galaxies in the GAMA and DustPedia samples. SF E/S0 and SF LBS galaxies are represented with blue and cyan symbols, respectively, while Q E/S0 galaxies (given that Q LBSs are under-represented and are not shown here; see Sect. 2.2) are shown with red symbols. Blue and red stars stand for the GAMA SF and Q S0 galaxies, while E sources are represented by circles. Open symbols show the DustPedia E/S0 galaxies. All values are plotted along with their corresponding uncertainties. Solid lines are the linear fits for the GAMA SF and Q galaxies (blue and red, respectively), while the dashed lines are the linear fits for the DustPedia SF and Q galaxies (blue and red, respectively).
