Histograms of: left: the luminosities for the variable (dark blue) and non-variable (light blue) galaxies in the sample; and right: the luminosities for the galaxies in the sample divided into Compton-thick (purple), Compton-thin (red), and changing-look (orange) candidates. The dashed line represents the value for the selection of faint (below) and bright (above) Seyfert 2s.
