Stellar mass surface density (Σ_⋆) arm/interarm contrast measured from NIR imaging as a function of the equivalent contrast from MUSE (Pessa et al. 2023). These sanity checks are possible for a subset of 13 galaxies and for a more limited field of view. The right panel demonstrates that the agremeent improves when applying the ICA correction (Sect. 2.5) to the Spitzer 3.6 μm maps. The median absolute deviation drops from 0.08 to 0.03 dex.
