Intensity maps at 230 GHz for the comparison test, with a resolution of 4096 × 4096 pixels. The RAPTOR output (top left panel) and BHOSS output (top right panel) show excellent agreement in total flux density. The relative difference between the output of both codes is plotted in the bottom left panel. The deviations become quite large in the periphery of the image; since the intensity in these regions is low, however, they do not contribute significantly to the integrated flux density, as can be seen in the absolute difference between the two codes (bottom right panel).
