Comparisons of the spatially resolved stellar population properties for 6958 pixel bins in the 25 sample galaxies derived from spatially resolved SED fitting with a nonparametric SFH model. The depicted physical properties include the stellar mass surface density (Σ_★), the SFR surface density (Σ_SFR), the stellar metallicity (Z_★), and the mass-weighted stellar age (t_★,  mw). The colors indicate the average trend with the dust optical depth in the V band (${\widehat{\tau }}_{\mathrm{dust},2}$), calculated with the LOESS method. Each hexbin includes a minimum of five points. Contours enclose 20%, 50%, and 80% of the total data. The dashed orange line represents the one-to-one relation. The Spearman’s correlation coefficient (ρ), measured bias (average offset μ), and scatter (standard deviation σ) relative to the ground truth from TNG50 are indicated in the legend of each panel.
