Fits to the far-IR data points from the Elbaz et al. (2011) GOODS-Herschel catalogue, using two templates of star forming galaxies (M 82 and Arp 220 in solid red and dashed blue, respectively) as well as two AGN templates (QSO2 and Seyfert 2 in dot-dashed green and dotted cyan). Only the infrared > 8 μm catalogue data were used in the fit, and the optical to near-infrared data are only shown here for comparison. The numbers in the bottom right of each panel show the integrated 8−1000 μm luminosities in solar units for each template.
