The redshift and luminosity distributions for the sources in our sample. (a) Upper panel: Comparison of the redshift distribution for the sources in our sample according to their origin. Sources found in BAT surveys are shown with gray histogram, sources with X-ray data missed by BAT survey are displayed with red-dashed line and sources without X-ray data are shown with the hatched histogram. (b) Lower panel: Similar as above for the L_12 μm luminosity obtained from Asmus et al. (2020).
