Examples of residual maps of the stellar properties of two TNG50-SKIRT Atlas galaxies, obtained from the nonparametric SFH configuration. The residual maps include the stellar mass surface density (Σ★), the SFR surface density (ΣSFR), stellar metallicity (Z★), and mass-weighted stellar age (t★,  mw). Each residual map is computed as the logarithmic ratio of the inferred property from Prospector to the ground truth value from TNG50, expressed as log10(Prospector/TNG50).
