Distribution of disk inclination for galaxies from the morphological sample, after removing bulge-dominated galaxies and those with small disk sizes. We show the distribution before correcting for the finite thickness of the disk (black line) and after the correction (red hatched area). The dashed orange line represents the binned theoretical distribution expected for randomly oriented disk galaxies. The correction tends to increase the fraction of edge-on galaxies. While being closer to the theoretical distribution at large inclinations, the corrected inclinations still do not match the distribution of randomly inclined galaxies.
