Subaru/XMM-Newton Deep Survey X-Ray Source List SXDSCAT ivo://nasa.heasarc/sxdscat NASA/GSFC HEASARC Ueda et al. 2026-10-09 NASA/GSFC HEASARC help desk heasarc-vo at athena.gsfc.nasa.gov Survey Source This table contains the X-ray source catalog in the Subaru/XMM-Newton Deep Survey (SXDS). A continuous area of 1.14 deg2 centered at R.A.= 02h 18m and Dec =- 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, the authors have detected 866, 1114, 645, and 136 sources with sensitivity limits of 6 x 10-16, 8 x 10-16, 3 x 10-15, and 5 x 10-15 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 deg2. Analyzing the autocorrelation function, the authors detect significant clustering signals from the 0.5 - 2 keV band sample, which can be fit with a power-law form (theta/thetac)(-0.8) with a correlation length of thetac of 5.9 (+1.0, -0.9) arcsec when the integral constraint term is included. In the 2 - 10 keV band, however, the clustering is not significant, with a 90% upper limit of thetac < 1.5 arcsec. This table was created by the HEASARC in November 2008 based on an electronic version of Table 2 of the reference paper obtained from the Astrophysical Journal website.
