THE SUBARU/XMM-NEWTON DEEP SURVEY (SXDS). III. X-RAY DATA

We present the X-ray source catalog in the Subaru/XMM-Newton deep survey. A continuous area of 1.14 deg(2) centered at R:A:= 02(h)18(m) and decl. = -05 degrees is mapped by seven pointings with XMM-Newton covering the 0.2-10 keV band. From the combined images of the EPIC pn and MOS cameras, we detect 866, 1114, 645, and 136 sources with sensitivity limits of 6; 10 X 16, 8; 10 X 16, 3; 10 X 15, and 5; 10 x 15 ergs cm(-2) s(-1) in the 0.5-2, 0.5-4.5, 2-10, and 4.5-10 keV bands, respectively, with detection likelihood >= 7 (corresponding to a confidence level of 99.91%). The catalog consists of 1245 sources in total including 32 extended-source candidates. The averaged log N-log S relations are in good agreement with previous results, bridging the flux range between Chandra deep surveys and brighter surveys. The log N-log S relations show significant spatial variation among pointings on a scale of 0.2 deg(2). Analyzing the autocorrelation function, we detect significant clustering signals from the 0.5-2 keV band sample, which can be fit with a power-law form (theta/theta(c))(-0.8) with a correlation length of theta c = 5.9(-0.9)(+1.0) arcsec when the integral constraint terms included. In the 2-10 keV band, however, the clustering is not significant with a 90% upper limit of theta(c) < 1.5 ''.
