Normalized q_IR distributions re-scaled to z₀ = 0.5 (q_IR, z0) for the control sample of VLBA non-detections (yellow histogram), while the 4 detections (light blue histogram) are shown both before (bottom panel) and after the VLBA AGN correction (top panel). The red Gaussian is the fit of the yellow+blue (or yellow) histograms, while the black curve is the Gaussian fit to the bootstrapped mirror distribution.
