我们提供了斯隆数字巡天数据发布7（DR7）类星体目录中105，783个类星体的属性汇编。在这个产品中，我们汇编了Hα，Hβ，Mg ii和C iv区域周围的连续谱和发射线测量，以及其他量，如射电性质，以及指示宽吸收线类星体，圆盘发射体等的标志。对于基准维里质量估计，我们使用Vestergaard & Peterson（VP 06）校准Hβ和C iv，以及我们自己的校准Mg ii，其平均匹配VP 06 Hβ质量。我们描述了这个目录的建设，并讨论其局限性。该目录及其未来的更新将在网上公开提供。
We present a compilation of properties of the 105,783 quasars in the Sloan Digital Sky Survey Data Release 7 (DR7) quasar catalog. In this product, we compile continuum and emission line measurements around the Hα, Hβ, Mg ii, and C iv regions, as well as other quantities such as radio properties, and flags indicating broad absorption line quasars, disk emitters, etc. We also compile virial black hole mass estimates based on various calibrations. For the fiducial virial mass estimates we use the Vestergaard & Peterson (VP06) calibrations for Hβ and C iv, and our own calibration for Mg ii which matches the VP06 Hβ masses on average. We describe the construction of this catalog and discuss its limitations. The catalog and its future updates will be made publicly available online.
