Planck Sunyaev-Zeldovich Cluster UNION List: Galaxy Clusters from Planck Satellite Data

Planck satellite data acquired between August 13, 2009 and November 26, 2010 was processed by three detection pipelines to identify galaxy clusters via the Sunyaev-Zel'dovich effect. The union catalog from the National Aeronautics and Space Administration contains coordinates, signal-to-noise ratios, and external validation information for these detections. This dataset is a component of the Planck mission's Data Release 1.

Use Cases

• Validate galaxy cluster detection pipelines based on the union of three independent methods (MMF1, MMF3, PwS).
• Study the spatial distribution of galaxy clusters based on provided coordinates.
• Assess detection reliability based on the signal-to-noise ratio data.
• Cross-reference cluster identifications and redshifts with external catalogs using the summary validation information.

Strengths

• Data originates from the Planck satellite mission, a major space observatory.
• Includes results from three independent detection pipelines for expert assessment.
• Covers observations from a defined period (August 2009 to November 2010).
• Provides external validation information, including redshift where available.

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.
