Cumulative number counts (number of sources brighter than a given flux) for the main source catalog (red dots) in the full (top), soft (middle), and hard (bottom) bands. The blue dot-dashed line represents the cumulative number of sources from our mock catalog. For comparison, we plot the log(N)–log(S) relations found in the 7 Ms Chandra Deep Field-South by Luo et al. (2017, magenta line), and in the COSMOS field by Civano et al. (2016, green dotted line).
