Radial distributions of Σ_*, Σ_SFR, sSFR, and EW_Hα for various stellar-mass ranges. Gray lines represent individual galaxy profiles, with the radius sampled in steps of 0.2R_e along the semimajor axis. Black lines indicate the location of the bulge for the same galaxy. Median profiles are color coded by stellar-mass range, blue (log(M_*/M_⊙) ≤ 9.5), green (9.5 < log(M_*/M_⊙) < 10), and red (log(M_*/M_⊙) ≥ 10). Solid lines correspond to LSB galaxies, and dashed lines to HSB galaxies. Shaded areas reflect the errors of the median profile.
