XLF of the intrinsic soft band (0.5 − 2.0 keV) for the AGNs in the lightcone. The luminosities are not corrected for Galactic absorption. We report the results for both the detected population (dotted blue line) and the entire population (solid blue line). In orange, we plot the XLF extracted from the mock catalogue in Marchesi et al. (2020) properly rescaled to account for the survey volume difference. The shaded band illustrates the Poisson uncertainty.
