Comparison between H I and optical geometric parameters. Left: Comparison of optical and H I inclinations with purple circles corresponding to optical inclinations obtained by assuming intrinsic thickness of q₀ = 0.3, and white circles corresponding to optical inclinations for a razor thin stellar disk. Middle: Difference in optical and H I inclinations with respect to the difference in the optical and H I morphological position angles. Right: Histogram of the cosine values of inclinations obtained from H I in blue and optical in orange. The number in the legend corresponds to the number of galaxies with well constrained inclinations. We note that all six galaxies in the last H I bin to the right show consistency with inclinations down to 0°.
