Planck Catalog of Compact Sources (PCCS): 30GHz Galactic and Extragalactic Objects

The Planck Catalogue of Compact Sources (PCCS) is a sample of reliable Galactic and extragalactic sources extracted from Planck satellite maps. It consists of nine independent source lists, one for each of Planck's frequency channels, derived from data acquired between August 13, 2009 and November 26, 2010. The catalog was released by the National Aeronautics and Space Administration as part of Planck Data Release 1.

Use Cases

• Cross-matching astronomical sources across nine microwave frequencies based on the independent channel lists.
• Analyzing flux densities of compact objects at 30GHz and adjacent frequencies based on the described column structure.
• Studying the population and distribution of Galactic and extragalactic sources identified by the Planck satellite.
• Validating source detection algorithms against a catalog of reliable sources extracted from nominal maps.

Strengths

• Contains source lists for nine distinct frequency channels, enabling multi-frequency analysis.
• Derived from over a year of Planck satellite data (August 2009 to November 2010).
• 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.
• Data may reflect temporal bias inherent to the specific 2009-2010 observation period.
