Number of AGN in different redshift and luminosity bins expected to be detected in the course of the four-year survey in the soft (top) and hard (bottom) bands. White empty bins with no number correspond to zero sources. The dotted line corresponds to the detection limit of eRASS. In the soft-band plot, the numbers in brackets are for the XLF without the exponential redshift cutoff, they are given only if the difference exceeds 10%.
