Top panel: ratios between S_I measurements of isolated, compact, deconvolved sources, within 30% of the primary beam power level in overlapping LoTSS-DR2 pointings that are predominantly separated in declination. These are projected onto the sky with the position being the mean position of the overlapping pointings and the colour scale indicates the best fit ratio between the S_I values. Bottom panel: median LoTSS to NVSS S_I ratios (divided by 5.936 to centre on unity) for different segments of individual fields averaged together for all LoTSS-DR2 fields with a declination less than 50°. Here 0° is North, the angle increases from North through West and the segments extend up to 2° from the pointing centres.
