我们提出了一个高银河系纬度的目录（|B|全天空X射线图像/气体狭缝相机（MAXI/GSC）监测器前37个月数据中探测到的X射线源。为了达到最佳的灵敏度，我们开发了一个背景模型的GSC，以及再现数据的基础上详细的板载校准。源检测是通过图像拟合与泊松似然算法。该目录包含500个在4-10 keV波段探测到的sD，4-10 keV的天体。在4-10 keV波段，50%的测量区域的极限灵敏度为10.75 × 10−12 erg cm−2 s−1（10.6 mCrab），这是覆盖该能量波段的全天测量使命中所达到的最高灵敏度。我们总结了该星表的统计特性和与Swift/BAT 70月星表、X射线探测星系团元星表和MAXI/GSC 7月星表交叉匹配的结果。我们的星表列出了296个源的名称（2 MAXI）、位置及其误差、4-10 keV和3-4 keV波段的探测意义和通量、硬度比以及可能对应源的基本信息。
We present a catalog of high Galactic-latitude (|b| > 10°) X-ray sources detected in the first 37 months of data of the Monitor of All-sky X-ray Image/Gas Slit Camera (MAXI/GSC). To achieve the best sensitivity, we develop a background model of the GSC that well reproduces the data based on the detailed on-board calibration. Source detection is performed through image fits with a Poisson likelihood algorithm. The catalog contains 500 objects detected with significances of sD, 4–10 keV ⩾ 7 in the 4–10 keV band. The limiting sensitivity is ≈7.5 × 10−12 erg cm−2 s−1 (≈0.6 mCrab) in the 4–10 keV band for 50% of the survey area, which is the highest ever achieved in an all-sky survey mission covering this energy band. We summarize the statistical properties of the catalog and results from cross matching with the Swift/BAT 70 month catalog, the meta-catalog of X-ray detected clusters of galaxies, and the MAXI/GSC 7 month catalog. Our catalog lists the source name (2MAXI), position and its error, detection significances and fluxes in the 4–10 keV and 3–4 keV bands, the hardness ratio, and the basic information of the likely counterpart available for 296 sources.
