Comparison of the normalized cumulative stellar mass growth curves of all 25 galaxies in our sample. We plot the cumulative stellar mass growth curves from the global nonparametric SFH inferred from our fiducial spatially resolved run (SFH_res,  np; orange), the global parametric SFH inferred from the spatially resolved map (SFH_res,  τ; pink), the nonparametric SFH derived from fitting the integrated photometry (SFH_{glob,  np}; yellow), the global parametric SFH based on a simple τ-model (SFH_{glob,  τ}; blue), and the true global SFH from the TNG50 resolved map (SFH_{res,  TNG50}; green). The dotted lines indicate the different formation times by which 20%, 50%, and 80% of a galaxy’s stellar mass was formed. Both nonparametric SFHs (SFH_res,  np and SFH_{glob,  np}) seem to be in better agreement with SFH_{res,  TNG50}, while most of the parametric SFHs (both SFH_res,  τ and SFH_{glob,  τ}) are skewed toward a later cosmic time, thus lacking the contribution from the older stellar populations.
