High-resolution H I moment maps of NGC 1371. Left panel: Primary beam-corrected H I column-density map. The contour levels are given on the colour bar. In the bottom right we show the 13.7″ × 9.6″ beam. The 10 kpc reference scale is shown in the top left. Central panel: Intensity-weighted mean velocity field with respect to the systemic velocity (1456.4 km s⁻¹). The dashed contours refer to the approaching side, while the solid lines correspond to receding velocities. Right panel: moment 2 map, i.e. the velocity spread along each LoS. It corresponds to the velocity dispersion when the emission comes from a single line or to the spread of multiple components at different velocities.
