Notes. In parentheses, we report the fraction of sources belonging to each class with respect to the total number of sources detected in a given energy range. Spurious detections, not reported in this table, are always < 0.5% of the overall detections. “Flux 20%” and “Flux 80%” are the flux limits reached over 20% and 80% of the proposed survey area, respectively: the Full and Hard band fluxes are computed in the 0.5–10 keV and 2–10 keV bands for an easier comparison with previous works, but the detections are obtained in the 0.5–7 keV and 2–7 keV bands.
