Planck PCCS 857GHz: Compact Galactic and Extragalactic Sources

The Planck Catalogue of Compact Sources (PCCS) is a sample of reliable sources extracted from Planck satellite maps. This 857 GHz component of Data Release 1 contains source lists derived from data acquired between August 13, 2009 and November 26, 2010. It is published by the National Aeronautics and Space Administration.

Use Cases

• Cross-matching and identifying compact sources based on the multi-frequency flux densities.
• Analyzing source properties and reliability based on the 24 columns per source.
• Studying the spectral energy distribution of sources using flux densities at 217, 353, 545, and 857 GHz.
• Validating and comparing source catalogs from other astronomical surveys.

Strengths

• Derived from the Planck satellite's nominal maps, a primary space-based observatory.
• Contains multi-frequency data with flux densities and uncertainties at four bands (217, 353, 545, and 857 GHz).
• Covers a defined observation period from August 2009 to November 2010.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
