Correlations of AV vs. FUV − NUV (left) and ﹩\mathrm{log}\,{\mathrm{sSFR}}_{\mathrm{NUV},\mathrm{cor}}﹩ vs. ﹩{(\mathrm{NUV}-B)}_{\mathrm{dc}}﹩ (right) for global (integrated) SFGs. The red line in the left panel is the best linear fit to the relation. The red line in the right panel is the best polynomial fit to the relation. The two plots will be used as calibrations to infer dust and sSFR radial profiles of the galaxies in this study.
