论文摘要
SDSS-DR16的类星体超集和管道目录被搜索未申报的类星体，这些类星体被隐藏或与其他物体混淆，通常是由于不完整的脱核而造成的。发现了四十种带有红移的类星体，并在此提出。另外，SDSS-DR16Q主排量目录中的82个条目被证明是非Quasars，有些也是由于不完整的融合，尤其是“偷猎者”。其他非Quasars被证明是恒星尖峰或移动的恒星或其他类型，并且通过对“插入”光谱的分析来确定7种新的类星体。与数百万的DR16光谱相比，这些数字很小，但突出了一些迄今为止被忽略的系统学。整个过程中都讨论了融合问题。
The SDSS-DR16 Quasar Superset and pipeline catalogues are searched for undeclared quasars which were concealed by or confused with other objects, usually due to incomplete deblending. Forty such quasars with redshifts are found and herewith presented. Also, 82 entries in the SDSS-DR16Q main quasar catalogue are shown to be non-quasars, some also due to incomplete deblending, especially "line poachers". Other non-quasars are shown to be star spikes or moving stars or other types, and 7 new quasars are identified from analysis of "unplugged" spectra. These numbers are tiny compared with the millions of DR16 spectra, but highlight some heretofore overlooked systematics. The deblending issue is discussed throughout.
