SFHs for the full galaxy sample. Each system is shown in a vertical three-panel block. Top: SFR(R_birth), the SFH binned by stellar birth radius. Middle: SFR(R_final), the SFH binned by present-day stellar radius. Bottom: fractional difference between the two, ∆SFH_fr. Across the sample, a consistent pattern emerges: early inner-disk star formation is underestimated in SFR(R_final), while outer-disk star formation is strongly overestimated at intermediate ages, with fractional biases often exceeding 200%. These systematic effects reflect the redistribution of stars via radial migration.
