Dependence of MCV behavior on intrinsic variability and bolometric luminosity. Left: distribution of individual RQ Seyfert 1s in the Lbol–σm[W2] parameter space. Rectangular bins indicate the 0.3 × 0.3 dex regions used for ensemble analysis. Right: median ρPearson for each bin, demonstrating that the negative correlation between σm[W2] and ρPearson persists even after controlling for Lbol.
