Redshift distribution of the 3515 sources with ANNz photo-z estimates in the X-ATLAS field (solid line) and the N(z) using TPZ (normalized to the number of sources with ANNz estimates) of the 65 sources that also belong to our X-ray AGN sample. The redshift distribution of the photo-z estimated by ANNz peaks at low redshifts (z ~ 0.3), and very few sources have z > 1 (solid line). This is expected since ANNz has been trained to estimate photometric redshifts for galaxies. The N(z) estimated using TPZ has been specifically trained to estimate photo-z for X-ray sources and presents a second peak at z ~ 1.5 (dotted line).
