Differential number counts as a function of flux produced by the LD+AD model (black) in the left: 2–10 keV energy range; centre: 8–24 keV range; and right: 14–195 keV range. The error bars represent the 68% confidence interval of the model based on the posterior of the parameters. For comparison, we present the differential number counts of the 70-month Swift/BAT (Ananna et al. 2022, green), combined NuSTAR (Harrison et al. 2016, brown), 4 Ms CDFS (Lehmer et al. 2012, red), XMM-CDFS (Ranalli et al. 2013, blue), and 2XMM (Mateos et al. 2008, magenta) surveys.
