Comparison of the predicted rest-frame 5 GHz luminosity from the best-fit fundamental plane (x axis) and the observed rest-frame 5 GHz luminosity (y axis) for the radio-quiet AGNs (left panel) and the radio-loud AGNs (right panel). The dashed black line in each panel represents the 1:1 line. The empty dark red triangles in the right panel represent the radio-loud AGNs with only upper limits for L_X (see parameter calculation in Section 3.3 and see sample selection in Section 5) that were not utilized in the regression fitting for the fundamental plane.
