Planck Catalog of Compact Sources: 44GHz Microwave Sky Objects

Nine independent lists of reliable Galactic and extragalactic sources extracted from Planck satellite maps between August 13, 2009 and November 26, 2010. The Planck Catalogue of Compact Sources (PCCS) is a component of Planck Data Release 1, with 24 columns per source at most frequencies and six additional columns for flux densities at adjacent frequencies in the 857 GHz list. It was produced by the National Aeronautics and Space Administration.

Use Cases

• Cross-matching sources with other astronomical surveys based on the nine frequency-specific lists.
• Analyzing spectral energy distributions of compact objects based on flux densities at adjacent frequencies for the 857 GHz sources.
• Studying the distribution and properties of Galactic versus extragalactic sources identified in the Planck maps.

Strengths

• Data acquired over a 15-month period, providing a consistent temporal baseline.
• Contains nine independent source lists, one for each of Planck's frequency channels.
• The 857 GHz list includes six additional columns for flux densities and uncertainties at three lower adjacent frequencies.

Limitations

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