SED results for the Pascucci et al. (2004) 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 reference code from Pascucci et al. (2004) (RADICAL; gray circles), for the three viewing angles used (12.5, 42.5, and 77.5°). The dashed line shows the blackbody spectrum of the central source. The bottom three sections in each panel show the fractional difference between Hyperion and RADICAL (black line), and between the other codes in Pascucci et al. (2004) and RADICAL (gray lines).
