Fig. 8.

LoTSS DR2 144 MHz image with 6″ angular resolution overlaid with 20″ LoTSS contours. Black contours represent 15 linearly spaced levels between 0.000435 and 0.4995 Jy beam⁻¹, with the first contour at 3σ. The top-left inset shows an optical image overlaid with a VLASS image at 2.5″ resolution. II and III markings indicate the second and outermost lobes (see Sect. 4.7).
