Optical and H I morphologies of AGC 114905. Left: optical colour image of the stellar disc generated using the filters g, r and i. The black and white background was created using the g-band image. For reference, scales of 5 arcsec and 3 kpc (assuming a distance of 78.7 Mpc) are shown. Middle: H I total intensity map with H I column density contours overlaid. The contours are at 1, 2, 4 × 10²⁰ cm⁻², and the noise of the H I column density map is 4.1 × 10¹⁹ cm⁻². The grey ellipse shows the beam of the observations. Right: H I column density map overlaid on the optical emission.
