Planck Catalog of Compact Sources: 545GHz Frequency Channel List

Between August 13, 2009 and November 26, 2010, the Planck satellite acquired data used to create the Planck Catalogue of Compact Sources (PCCS). This catalog, a component of Planck Data Release 1, is a sample of reliable Galactic and extragalactic sources extracted from Planck's nominal maps. The National Aeronautics and Space Administration (NASA) provides this 545 GHz frequency channel list, which includes flux densities from adjacent frequencies.

Use Cases

• Cross-match compact sources with other astronomical catalogs based on the provided flux densities and positions.
• Analyze source spectral energy distributions based on flux densities at multiple frequencies (217, 353, 545 GHz).
• Identify and classify Galactic versus extragalactic objects from the curated sample of reliable sources.
• Validate source detection algorithms using the independently extracted source lists from nine frequency channels.

Strengths

• Data acquired over a defined 15-month period from August 2009 to November 2010.
• Catalog consists of nine independent source lists, one for each of Planck's frequency channels.
• The 545 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 for specific analysis scales.
