Histogram and Gaussian kernel density estimation of the difference in magnitude of root-mean-square residuals in annuli around bright source, screen-corrected, σ_screen, over LoTSS-DR2 archival, σ_DR2. The root-mean-square residuals are calculated within an annulus between 12″ and 90″ centred on sources brighter than 0.1 Jy beam⁻¹. The residuals are primary-beam uncorrected. The black line denotes the mean ratio, and corresponds to σ_screen = 0.68σ_DR2.
