NGC 1371 H I channel maps from 1250 km s⁻¹ to 1665 km s⁻¹ in steps of 28 km s⁻¹. The coloured contours correspond to column densities of (4.3, 8.6, 17.3, 34.5) × 10¹⁸ cm⁻², equivalent to (4, 8, 16, 32)σ. The dashed grey contours denote the column density of −4.3 × 10¹⁸ cm⁻². At the bottom, we report the LoS velocity (with respect to the systemic velocity) in each channel and at the top left the 10 kpc reference scale. In the bottom right corner the 13.7″×9.6″ beam is displayed.
