Zeroth-moment map of the region around the NGC 7424 absorbers in greyscale. The map was created by collapsing channels of the r00_t00 data cube between 866.4 and 867.6 km s⁻¹, corresponding to the velocity range of the SN2001ig absorption feature. No masking was applied. Cyan contours show the H I column density at 0.005 and 0.01 Jy beam⁻¹ km s⁻¹ (corresponding to 1.1 × 10²⁰ and 2.2 × 10²⁰ cm⁻², respectively). Crosses indicate the positions of the continuum sources. Annuli with inner radius one beam width and outer radius two beam widths are overplotted and bisected by dashed lines at a position angle of −18°. The r00_t00 beam is shown in the lower right.
