我们给出了使用SWIFT伽马射线暴天文台的爆发警报望远镜(BAT)硬X射线探测器在70个月的观测中探测到的源的目录。SWIFT-BAT 70个月调查在14-195keV波段探测到1,171个硬X射线源(是之前22个月调查的两倍多)，显著水平降至4.8σ，与1,210个对应物相关。70个月的SWIFT-BAT观测是最敏感和最均匀的硬X射线全天观测，其通量水平达到1.03×10−11erg S−1 cm−2超过50%的天空和1.34×10−11erg S−1 cm−2超过90%的天空。在70个月的调查中，大多数新源仍然是活动星系核，目录中有700多个。作为新版SWIFT-BAT目录的一部分，我们还在在线期刊和SWIFT-BAT 70个月网站上提供了调查中检测到的每个物体的八通道光谱和每月采样光曲线。
We present the catalog of sources detected in 70 months of observations with the Burst Alert Telescope (BAT) hard X-ray detector on the Swift gamma-ray burst observatory. The Swift-BAT 70 month survey has detected 1171 hard X-ray sources (more than twice as many sources as the previous 22 month survey) in the 14–195 keV band down to a significance level of 4.8σ, associated with 1210 counterparts. The 70 month Swift-BAT survey is the most sensitive and uniform hard X-ray all-sky survey and reaches a flux level of 1.03 × 10−11 erg s−1 cm−2 over 50% of the sky and 1.34 × 10−11 erg s−1 cm−2 over 90% of the sky. The majority of new sources in the 70 month survey continue to be active galactic nuclei, with over 700 in the catalog. As part of this new edition of the Swift-BAT catalog, we also make available eight-channel spectra and monthly sampled light curves for each object detected in the survey in the online journal and at the Swift-BAT 70 month Web site.
