SED results for the Pinte et al. (2009) disk benchmark, for the four disk masses used. In each panel, the top section shows the SED obtained using Hyperion (black line), compared to the average result of the codes used in Pinte et al. (2009) (gray circles), for four of the viewing angles (18.2, 75.5, 81.4, 87.1°). The dashed line shows the blackbody spectrum of the central source. The bottom four sections in each panel show the fractional difference between Hyperion and the reference result (black line), and between the other codes compared in Pinte et al. (2009) and the reference result (gray lines).
