Top left: IRAC 3.6 μm image of the NGC 5291 system. A linear stretch between −0.04 and 1.6 MJy sr⁻¹ is used. The scale bar represents 1^{﹩\arcmin﹩}, i.e., a linear scale of 18 kpc. Top right: IRAC 4.5 μm image. A linear stretch between −0.05 and 1.2 MJy sr⁻¹ is used. Bottom left: IRAC 5.8 μm image. A linear stretch between −0.13 and 0.71 MJy sr⁻¹ is used. Bottom right: IRAC 8.0 μm image. A linear stretch between −0.10 and 0.72 MJy sr⁻¹ is used.
