Ratio of observable H I in the filtered image to observable H I in the smoothed image for Blizzard at various observed inclinations and position angles (at z = 0, D = 20 Mpc). This isolates the effect of missing short baselines. Imaging parameters correspond to MHONGOOSE-LR. Projections on the top and right show the ideal H I column density maps at various orientations. There is a general increase in this ratio at higher inclination, as edge-on galaxies appear more compact on the sky. At lower inclinations, there is little dependence on position angle; however, there is a clear pattern at higher inclinations. When the galaxy is more edge-on, there are two regions of lower observability at position angles of ∼100° and ∼280° corresponding to when the warped component of the disk is face-on with the observer, causing dips in the observable CGM ratio.
