Left-hand plot shows the overall obscured fraction of AGNs (type-2 s plus red type-1s) declining rapidly as a function of luminosity. We also show separately the fraction of heavily obscured, type-2 objects and lightly obscured, type-1 objects. The right-hand plot shows the obscured fraction split by redshift into low (﹩z\lt 0.8﹩) and high (﹩z\gt 0.8﹩) bins. The measured ratios are shown as points with errorbars, the ratios of the luminosity functions of each type to the overall AGN luminosity function (both luminosity functions integrated over the range in redshift that a given luminosity could be detected in our survey) are shown as dashed lines.
