Planck Catalog of Compact Sources: 143GHz Frequency Channel

The Planck Catalogue of Compact Sources (PCCS) is a sample of reliable Galactic and extragalactic sources extracted from Planck satellite maps. This 143GHz catalog is part of Planck Data Release 1, derived from data acquired between August 13, 2009 and November 26, 2010. It is produced by the National Aeronautics and Space Administration.

Use Cases

• Cross-matching compact sources with other astronomical surveys based on the catalog's frequency-specific extraction.
• Analyzing source flux densities and uncertainties for spectral energy distribution studies.
• Studying the distribution of Galactic and extragalactic compact objects at microwave frequencies.

Strengths

• Data acquired over a defined 15-month observation period from August 2009 to November 2010.
• Catalog is a component of the official Planck Data Release 1, indicating a formal data product.
• Source lists contain 24 columns per source, suggesting multiple measured attributes.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
