Description

We present results of cosmological redshift measurements for X-ray AGNs discovered by eRosita in the Lockman Hole extragalactic field during the SRG PV-phase survey. Photometric redshifts and related classification (absorbed/unobsorbed AGN) of X-ray sources were performed by machine learning photo-z models implemented in SRGz package. We discuss the importance of different photometric data from modern sky surveys (GAIA, SDSS, PanSTARRS, Legacy Surveys, WISE) in reaching the goal of high accuracy and low outlier rate photo-z predictions.
