Cumulative luminosity function for the 88 sources detected in BB335B_C (of the total 97 sources detected in all epochs). To be directly comparable with Fig. 1 of Chomiuk & Wilcots 2009, the luminosities have been extrapolated from Tables 3 and 4 to 1.45 GHz, assuming a spectral index of −0.5. A power-law fit it shown as a solid line. The point source detection limit is shown as a vertical black dashed line to the left, and fitted completeness limit (where the power law turns over) is shown as a dotted line.
