Mean A₂ radial profiles as a function the morphological type (left column) and the stellar mass (right column), computed from the Fourier amplitudes of individual galaxies rescaled to a common frame determined by R_25.5. Barred (green dashed line) and non-barred (orange solid line) systems are studied separately, based on the morphological classification by B2015. We also divided the bin of barred galaxies into weakly (B+SAB, dotted line) and strongly (+SB, solid line) barred galaxies. The vertical dotted lines indicate the mean bar size, relative to R_25.5, of the galaxies in the bin. Ten galaxies whose disks did not extend as far as 0.8R_25.5 were excluded from this analysis. The standard deviation of the mean for barred and non-barred systems is indicated with vertical lines.
