Scatter plot of the peak and median source brightness, coloured by source type. Histograms on the top and right show the counts per source type relative to each of the variables, in log scale. The solid line represents S_max = S_median, and the dashed lines indicate the upper limit of the nominal off-source rms (10–20 µJy beam⁻¹; Goedhart et al. 2024). Sources with median source brightness below this threshold (e.g. due to negative bowls) have been excluded from the plot.
