H I moment maps for VGS 12 at three distinct resolutions: ∼17″ (top row), ∼9″ (middle row), and ∼5″ (bottom row). The left panels show the H I contours overlaid on DECaLS g-band optical images. The plotted H I contours, starting at the 2σ level, are 3.7 × 10¹⁹ × ($\sqrt{3}{)}^n$ atoms cm⁻², n = 0, 1, 2, 3,...at 17″, 7.4 × 10¹⁹ × ($\sqrt{3}{)}^n$ atoms cm⁻², n = 0, 1, 2, 3,...at 9″, and 20.3 × 10¹⁹ × ($\sqrt{3}{)}^n$ atoms cm⁻², n = 0, 1, 2, 3,...at 5″. The middle panels display velocity fields (isovelocity contours are spaced at intervals of 20 km s⁻¹), while the right panels present Moment 2 maps. The Gaussian beam is shown on the bottom left of each map.
