我们给出了斯巴鲁/XMM-牛顿深度探测中的X射线源目录。以R.A.为中心的1.14°2的连续区域。=02h18m和Decl。=−05°由7个点映射，其中XMM-牛顿覆盖0.2-10keV带。从EPIC pn和MOS相机的组合图像中，我们在0.5-2，0.5-4.5，2-10和4.5-10keV波段分别探测到866,1114,645和136个源，灵敏度下限分别为6×10−16，8×10−16，3×10−15和5×10−15 ergs cm−2 S−1，探测似然≥7(对应于99.91%的置信度)。该目录共有1245个来源，其中包括32个扩展来源候选来源。平均的对数N-对数S关系与前人的结果吻合较好，弥补了钱德拉深部调查和较亮调查之间的通量范围。点与点之间的对数N-对数S关系在0.2°2的尺度上表现出显著的空间变异。通过对自相关函数的分析，我们从0.5-2keV频段的样本中检测到了显著的聚簇信号，当包含积分约束项时，可以用幂函数形式(θ/θc)−0.8来拟合，相关长度θc=5.9+1.0−0.9角秒。然而，在2-10keV波段，聚集性并不明显，90%的上限是θc<；1.5“。
We present the X-ray source catalog in the Subaru/XMM-Newton deep survey. A continuous area of 1.14 deg2 centered at R .A . = 02h18m and decl . = − 05° 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 × 10−16, 8 × 10−16, 3 × 10−15, and 5 × 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, we detect significant clustering signals from the 0.5-2 keV band sample, which can be fit with a power-law form (θ/θc)−0.8 with a correlation length of θc = 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 θc < 1.5″.
