DECaLS optical g, r, and z band color-composite images of galaxies in the LARS and eLARS samples with HI 21 cm column density contours overlaid. The contours have fixed levels of 2ⁿ × 10¹⁹ cm⁻², with n = 0, 1, 2, …, 5. White contours have S/N ≥ 3, while the low signal-to-noise contours are shown in gray. All images are 300 × 300 kpc², and are centered upon the coordinates of the galaxies. The contours show the main SoFIA 2 detection, apart from eLARS05 and eLARS10 for which an ancillary detection is shown in grey to the south east. A star on the lower right corner of a panel indicates the galaxy has been identified as undergoing interaction.
