X-ray (2keV) luminosity-redshift distribution for eRASS1 sources within the LS10 footprint, compared to the same distribution from the high purity and reliability AGN sample DR1_LS10_EXGAL_DET6P90 (blue). Symbols indicate the redshift: spectroscopic (red) and photometric (black). The apparent excess of sources at z = 6 is attributed to unreliable photometric redshift estimates (see Section 6). For completeness, the histogram distributions for the redshift (top) and the X-ray luminosity (right) are also shown. In the redshift distribution we also show, in orange, the spectroscopic distribution for sources at the depth of ROSAT (F_{0.5 − 2 keV} > 2 × 10⁻¹³ erg s⁻¹ cm⁻²).
