Planck Catalog of Compact Sources 70GHz Catalog

The Planck Catalogue of Compact Sources (PCCS) is a sample of reliable sources, both Galactic and extragalactic, extracted directly from the Planck nominal maps. The first public version of the PCCS, a component of Planck Data Release 1, is derived from the data acquired by Planck between August 13 2009 and November 26 2010. The PCCS consists of nine lists of sources, extracted independently from each of Planck's nine frequency channels. The source lists contain 24 columns per source at the LFI and HFI bands. 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. 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.

普朗克紧凑源目录（Planck Catalogue of Compact Sources, PCCS）是直接从普朗克标准地图中提取的可靠源样本，涵盖银河系内与河外星系两类源。作为普朗克第一批次数据发布（Planck Data Release 1）的组成部分，该目录的首个公开版本源自普朗克望远镜于2009年8月13日至2010年11月26日期间采集的观测数据。普朗克紧凑源目录包含9组源列表，每组均独立从普朗克的9个频率通道中提取。针对低频仪器（Low Frequency Instrument, LFI）与高频仪器（High Frequency Instrument, HFI）波段的每个源，该源列表均包含24个数据列。857吉赫（GHz）源列表额外增设6列数据，用于提供3个相邻较低频率（217、353与545吉赫）下的流量密度及其不确定度。本数据集或服务由红外处理与分析中心（Infrared Processing and Analysis Center, IPAC）下属的红外科学档案馆（Infrared Science Archive, IRSA）提供，该中心由加州理工学院根据与美国国家航空航天局（National Aeronautics and Space Administration, NASA）的合同运营。
