Planck Catalog of Compact Sources: 100GHz Extragalactic and Galactic Sources

The Planck Catalogue of Compact Sources (PCCS) is a sample of reliable Galactic and extragalactic sources extracted from Planck satellite maps. This 100GHz catalog is part of Planck Data Release 1, derived from observations between August 13, 2009 and November 26, 2010. It is published by the National Aeronautics and Space Administration (NASA).

Use Cases

• Cross-matching astronomical sources based on nine independent frequency channel lists.
• Analyzing flux densities and uncertainties for sources at 100GHz and adjacent frequencies.
• Studying the statistical properties of Galactic and extragalactic compact sources from satellite data.

Strengths

• Data is derived from the Planck satellite's nominal maps, providing a direct observational source.
• Catalog consists of nine independent source lists, one for each of Planck's frequency channels.
• The 857 GHz list includes six additional columns for flux densities at three adjacent lower frequencies.

Limitations

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