a) Area detection efficiency as a function of 2−10 keV X-ray flux for the XXL-1000-AGN sample. These curves were used for the calculation of the number counts and the AGN luminosity function. b) log N−log S for the XXL-1000-AGN in the XXL-N field (blue circles) and in the XXL-S field (orange squares). The black points are the number counts of XMM-COSMOS, the red line shows the cumber counts from the H-ATLAS, and the grey line the number counts of XMM-CDFS.
