Planck PCCS2E 857GHz Catalog

The second Planck Catalogue of Compact Sources (PCCS2) is a set of single-frequency source catalogues extracted from the Planck full-mission maps in intensity and polarization. The 100, 143, 217, and 353 GHz catalogs include polarization measurements. The 857 GHz source list has six additional columns which give the flux densities and flux density uncertainties at the three adjacent lower frequencies: 217, 353, and 545 GHz. The PCCS2E catalogs consist of those sources detected in sky regions where the diffuse emission makes it difficult to quantify the reliability of the detections. This dataset or service is made available by the Infrared Science Archive (IRSA) at IPAC, which is operated by the California Institute of Technology under contract with the National Aeronautics and Space Administration.

第二代普朗克致密源星表（The second Planck Catalogue of Compact Sources, PCCS2）是一套从普朗克全任务天图的强度与偏振数据中提取得到的单频源星表集合。其中100 GHz、143 GHz、217 GHz及353 GHz频段的星表均包含偏振测量数据。857 GHz源列表额外增设六列数据，用于提供其在217 GHz、353 GHz与545 GHz三个邻近低频段的流量密度及流量密度不确定度。PCCS2E星表所收录的源均来自弥漫辐射较强、难以量化探测可靠性的天区。本数据集及相关服务由IPAC下属的红外科学档案库（Infrared Science Archive, IRSA）提供，该机构由加州理工学院依据与美国国家航空航天局签订的合同负责运营。
