摘要
我们呈现了基于斯隆数字巡天(SDSS)第七次数据发布的第五版SDSS类星体表。该星表包含105,783个经光谱证认的类星体，代表了SDSS-I和SDSS-II类星体巡天的终结。星表由满足以下条件的SDSS天体组成：光度大于M_i = -22.0（宇宙学参数H_0 = 70 km/s/Mpc, Omega_M = 0.3, Omega_Lambda = 0.7），至少有一条半高全宽大于1000 km/s的发射线或具有有趣/复杂的吸收特征，i波段星等暗于15.0，且具有高度可靠的红移。星表覆盖面积为9380平方度。类星体红移范围从0.065到5.46，中位值为1.49；星表包含1248个红移大于4的类星体，其中56个红移大于5。星表包含9210个i<18的类星体；略超过一半的条目i<19。对于每个天体，星表提供了精度优于每坐标0.1角秒均方根的位置、典型精度0.03星等的五波段(ugriz)CCD测光数据，以及形态和选择方法信息。星表还包含了来自其他大面积巡天的类星体射电、近红外和X射线发射特性（如有）。校准后的数字光谱覆盖波长范围3800-9200埃，光谱分辨率R=2000；可使用星表中提供的信息从SDSS公共数据库检索光谱。星表中超过96%的天体由SDSS发现。我们还附上了一个补充列表，包含另外207个具有SDSS光谱但其存档测光信息不完整的类星体。
