Distributions of the magphys derived SED properties for the SMG sample (red) and field (hatched grey, scaled down by a factor of 10) and massive field (M. Field) samples (open black histograms). We show the F444W AB magnitude (a), photometric redshift (b), stellar mass (c), star formation rate (d), specific star formation rate (e), infrared luminosity (f), dust mass (g) and V-band attenuation (A_V) (h). For each distribution, we indicate the bootstrapped median and uncertainty for SMGs (red marker and error bar) and the matched field (grey marker and error bar) and massive field sample (black marker and error bar). By construction, the less massive field sample mirrors the SMG sample in redshift and specific star formation rate distributions resulting in lower stellar masses, whilst the massive field sample more closely matches the SMGs distribution in stellar mass but with a lower median redshift. Both field samples have significantly lower dust masses, infrared luminosity, star formation rates and A_V.
