\caption{Spearman rank correlation test results for the whole sample and AGN subclasses for the log $\nu_{\rm p} L_{\rm p}$ vs. log $\nu_{\rm p}$ -correlation. On the left side is the $z$-corrected correlation, and on the right side the $D$-corrected one. Galaxies (GAL) have been omitted due to small sample size.}
