Radial H I surface density profiles of IRAS 04296+2923 and H I 0432+2926. For each galaxy, the profiles derived from the VLA–D and VLA–C configurations are shown in red and blue, respectively, with solid lines representing IRAS 04296+2923 and dashed lines representing H I 0432+2926. For comparison, the H I radial profile of NGC 253 from the KAT-7 observations (Lucero et al. 2015) is plotted as the solid black line.
