Disk fraction as a function of effective radius r_eff, measured in angular units with bin size Δr = 0.1 arcsec (top) and in physical units of Δr = 1 kpc (bottom). Blue points represent the disk fraction in each bin, and error bars indicate binomial uncertainties. Dashed lines are shown to guide the eye. In both panels, the disk fraction increases with effective radius, highlighting that disks are more easily identified in galaxies with larger apparent and physical sizes.
