H I velocity field. Velocities are in the barycentric reference frame (optical definition). The velocity colour bar is centred at the systemic velocity of NGC 1316, 1760 km s⁻¹. The black H I contour is the same as the first contour in Fig. 2 and has a column density of 2.7 × 10¹⁹ cm⁻². The grey, open ellipse represents the stellar body of NGC 1316. The Gaussian restoring PSF in the bottom-left corner has a FWHM of 36.7″ × 28.1″ and position angle 109 deg. The scale bar in the top-left corner represents 20 kpc (∼3.5′ at a distance of 20 Mpc). The H I properties of the labelled sources are listed in Table 2.
