Bersier et al. (1994) WebApr 8, 2024 · For ~1/3 of spirals, the approximation of axial ratios provides inclination estimates good to better than 5 degrees, with degradation to ~5 degrees for another 1/3. However in ~1/3 of cases, ellipticity-derived inclinations are problematic for a variety of reasons. Prominent bulges can dominate the axial ratio measurement. blanche a billet
