Planck Catalog of Compact Sources: 70GHz Microwave Sky Objects

Nine lists of reliable Galactic and extragalactic sources extracted from Planck satellite maps. The catalog is derived from data acquired between August 13, 2009 and November 26, 2010, as part of Planck Data Release 1. Each source list contains 24 columns, with the 857 GHz list having six additional columns for flux densities at adjacent frequencies.

Use Cases

• Cross-matching and identifying compact sources based on nine independent frequency channel lists.
• Analyzing flux densities and uncertainties for sources at 217, 353, 545, and 857 GHz.
• Studying the distribution and properties of Galactic versus extragalactic microwave sources.
• Validating source detection algorithms against Planck satellite nominal maps.

Strengths

• Contains nine independent source lists derived from Planck's nine frequency channels.
• Data covers a specific 15-month observation period from August 2009 to November 2010.
• Source lists include 24 columns per source, with additional columns for flux at adjacent frequencies in the 857 GHz list.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• File formats are BIN and PDF, which may require specialized tools for data access.
