Integrated flux density to peak brightness ratios of compact LoTSS-DR1 sources as a function of separation from the pointing centre for catalogues derived from individual LoTSS-DR1 pointings. The thick red curve shows the approximate ratio expected from time and bandwidth smearing assuming that unresolved sources have a ratio of 1.0. The effects of time and bandwidth smearing are taken into account during deconvolution in DDFacet. The red points show the median ratios within bins of distance; the 95% confidence intervals are ∼0.02 and were estimated by the bootstrap method. The horizontal errors bars give the bin width and the vertical dashed line shows the median distance between LoTSS pointings.
