SFR versus M_star (top panel) and f_abs versus L_bol (bottom panel) for the late-type (Sa-Scd and Sd-Irr) galaxies in the GAMA and DustPedia samples. SF Sa-Scd and Sd-Irr galaxies are represented with blue and yellow symbols, respectively, while Q Sa-Scd galaxies (given that Q Sd-Irr 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 Sa galaxies, while Sab-Scd sources are represented by circles. Open symbols show the DustPedia Sa-Irr 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).
