LoTSS DR2 image of the peculiar radio galaxy J0011+3217 in contours (levels: 0.23, 0.45, 0.75, 1.17, 1.75, 2.57, 3.72, 5.33, 7.58, 10.7, 15.1, 21.3, 30.0, 42.1, and 59.0 mJy beam⁻¹) overlaid on an image from the Pan-STARRS1 optical r band. The right panel is a zoomed-in view of the optical galaxies G1 and G2. The lowest contour level of J0011+3217 is at 3σ, where σ = 78 μJy beam⁻¹ is the RMS of the field. The synthesised beam of the LoTSS DR2 image (marked by the red circle in the lower-left corner of the image) has 6″ × 6″ resolution.
