Top: correlation between the IR luminosity and the rest-frame 150 MHz luminosity for the main spec-z sample, including AGNs identified in the X-ray, IR, the Million Quasar Catalog and in optical spectroscopy. The vertical dashed line indicates the 90% completeness limit at the median redshift (z ∼ 0.05) of the main sample. Bottom: same as top panel but for the second sample. The vertical dashed line indicates the 90% completeness limit at the median redshift (z ∼ 0.12) of the second sample.
