Abstract

ASCA Deep Sky Survey (DSS) is aimed to investigate the constituents of the CXB in 2-10 keV band, by faint source survey observations reaching to the source confusion limit of ASCA X-Ray Telescopes. So far, 0.29 deg2 sky regions were systematically studied and about 40% of the CXB intensity was resolved into discrete sources. In this paper, we present the latest results on the number-flux relation (LogN-LogS) and spectrum properties of faint X-ray sources.
