我们介绍了斯隆数字巡天III重子振荡光谱巡天（BOSS）的类星体数据发布9（DR 9 Q）目录。该目录包括在调查期间作为类星体候选者的所有BOSS对象，通过目视检查光谱学确认为类星体，亮度Mi[z = 2] 2.15（61 931）是以前已知的z > 2.15类星体数量的2.8倍。提供了最强发射线（C iv，C iii]，Mg ii）的红移和半高宽。该目录识别了7533个宽吸收线类星体，并给出了它们的特征。对于每一个对象的目录提供了五个波段（u，g，r，i，z）CCD为基础的测光与典型的精度为0.03等，和信息的形态和选择方法。该目录还包含X射线，紫外线，近红外线和无线电发射性质的类星体，如果可用的话，从其他大面积的调查。校准后的数字光谱覆盖3600−10 500 A波长范围，光谱分辨率范围为1300 < R < 2500;光谱可以从SDSS目录存档服务器中检索。我们还提供了一份补充清单，列出了另外949个已被识别的类星体，它们是BOSS的星系目标或DR 9被冻结后的类星体目标。
We present the Data Release 9 Quasar (DR9Q) catalog from the Baryon Oscillation Spectroscopic Survey (BOSS) of the Sloan Digital Sky Survey III. The catalog includes all BOSS objects that were targeted as quasar candidates during the survey, are spectrocopically confirmed as quasars via visual inspection, have luminosities Mi[z = 2] 2.15 (61 931) is ~2.8 times larger than the number of z > 2.15 quasars previously known. Redshifts and FWHMs are provided for the strongest emission lines (C iv, C iii], Mg ii). The catalog identifies 7533 broad absorption line quasars and gives their characteristics. For each object the catalog presents five-band (u, g, r, i, z) CCD-based photometry with typical accuracy of 0.03 mag, and information on the morphology and selection method. The catalog also contains X-ray, ultraviolet, near-infrared, and radio emission properties of the quasars, when available, from other large-area surveys. The calibrated digital spectra cover the wavelength region 3600−10 500 A at a spectral resolution in the range 1300 < R < 2500; the spectra can be retrieved from the SDSS Catalog Archive Server. We also provide a supplemental list of an additional 949 quasars that have been identified, among galaxy targets of the BOSS or among quasar targets after DR9 was frozen.
