Comparison between the new and old catalogues. From top to bottom, the N3, S11, and L15 catalogues are compared. Left: comparison of the fluxes for sources detected in the new and old catalogues. The green solid lines show the median line, blue dashed lines show line of unity. Right: the green dashed lines show the flux distribution of previous catalogue sources that are not detected in this work. The red solid lines show the expected number of missing objects, calculated from the completeness.
