Comparison of spatial maps generated by SKIRT for TODDLERS (top row), HiiM3 (middle row) models of AU-21, and the normalized difference between the two (bottom row). Columns show different bands centered at wavelengths listed on top. Images use a cube root scale. For each band, the images for both models share the same colormap limits, but the colormap limits may vary between bands. The data has been smoothed using a uniform filter of three pixels.
