Comparison of broad-band luminosity scaling relations between the DustPedia sub-sample DPD44 (blue stars) and SKIRT post-processed Auriga galaxies using the two available star-forming regions’ libraries in SKIRT, TODDLERS (red crosses), and HiiM3 (green crosses) at the calibrated parameter values. The Auriga sample in both cases consists of 60 points, including an edge-on and face-on configuration for each of the 30 Auriga galaxies. The rolling median lines use four bins of equal width in the K-band luminosity, L_K.
