AGN RLF split into redshift and ℳ_*. Coloured circles are the observed data points at each ℳ_*, which add up to make the total RLF (black circles) at that redshift. Vertical dotted lines indicate the 1.4 GHz luminosity at +2σ above the IRRC at a given (ℳ_*,z), which sets our L_1.4 threshold in the same bin to mitigate AGN incompleteness. Solid lines mark the best-fitting RLF obtained with PLE form. See Sect. 4.5 for details.
