The limiting sensitivity is 5 x 10<sup>-14</sup> erg/cm<sup>2</sup>/s (or mW/m<sup>2</sup>) where about 25% of the Cosmic X-ray Background (CXB) is resolved into discrete sources. The log N - log S function, built with a statistically complete sample of 177 sources, is steep and in good agreement with the counts derived from ASCA surveys. This database was created by the HEASARC in December 2000 based upon <a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/A+A/362/799">CDS Catalog J/A+A/362/799</a>.
