Colour scale of the 887 MHz ASKAP image zoomed into the area encompassing A3562 and SC 1329–313 (upper panel). Restoring beam and noise level are as in Fig. 2. Central panel: the 1.28 GHz MeerKAT image of the same region. The restoring beam is 6.9″ × 6.5″, p.a. 151.8°. The average noise level is ∼6 μJy beam⁻¹. The flux density colour scale is in the range −0.1 to 0.7 mJy. The labels highlight the features presented in this paper. Bottom panel: the colour scale of the 1.28 GHz MeerKAT filtered image of the same region, convolved with a beam of 40″ × 40″ (see Sect. 3.2), with contours (dashed red for negative) of the same image overlaid. The contours are plotted at ±0.1, 0.2, 0.4, 0.8 mJy beam⁻¹, the average noise level is ∼30 μJy beam⁻¹.
