Planck Catalog of Compact Sources: 217GHz Channel from 2009-2010

Nine lists of reliable Galactic and extragalactic sources extracted from Planck satellite maps. The first public version is derived from data acquired between August 13, 2009 and November 26, 2010. It was produced by the National Aeronautics and Space Administration as part of Planck Data Release 1.

Use Cases

• Cross-matching astronomical sources based on flux densities at nine frequency channels.
• Analyzing the distribution of Galactic versus extragalactic compact sources.
• Validating source detection algorithms using the reliable sample criteria mentioned.
• Studying spectral energy distributions using flux densities at adjacent frequencies for the 857 GHz list.

Strengths

• Contains nine independent source lists, one for each of Planck's frequency channels.
• Data collection spans a defined 15-month period from August 2009 to November 2010.
• The 857 GHz list includes six additional columns for flux densities at three lower frequencies.

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.
