FBQS quasar luminosities vs. redshift in the radio and optical. Left: Radio luminosity at a rest frequency of 5 GHz vs. redshift, using spectral index ﹩\alpha =-0.5﹩. Right: Absolute red magnitude vs. redshift, using spectral index ﹩\alpha _{\mathrm{opt}\,}=-1﹩ for the K‐correction. Dashed lines show 1 mJy FIRST detection limit and ﹩E=17.8﹩ APM magnitude limit. The radio luminosities have a much larger dynamic range and do not crowd as closely against the detection limit as do the optical magnitudes.
