The BR^Nu vs. redshift for the unobscured AGNs, obscured AGNs, CT AGNs, dual AGNs (Mrk 266 and NGC 6240), jet-dominant AGN (NGC 1275), 8–24 keV detected but starburst-dominant sources, and 8–24 keV undetected sources. The symbols are color coded by merger stage. The black dotted, dashed, and solid lines show the band ratio assuming an unobserved soft X-ray fraction of f_bin = 1% and ﹩{N}_{{\rm{H}}}^{\mathrm{LoS}}﹩ = 10²², 10²⁴, and 10²⁵ cm⁻², respectively.
