Planck Sunyaev-Zeldovich Cluster PwS List: Galaxy Clusters from Planck Data Release 1

Planck satellite data from August 13, 2009 to November 26, 2010 was processed by three pipelines to detect galaxy clusters via the Sunyaev-Zel'dovich effect. The catalogs, a component of Planck Data Release 1, provide coordinates, signal-to-noise ratios, and external validation information for candidate clusters. This specific list contains the results from the PowellSnakes (PwS) detection pipeline.

Use Cases

• Validate galaxy cluster detection algorithms based on the comparison of three independent pipelines (MMF1, MMF3, PwS).
• Study the distribution and properties of galaxy clusters based on coordinates and signal-to-noise ratios.
• Cross-match and validate cluster candidates based on external identification and redshift information.
• Analyze the performance of the PowellSnakes (PwS) detection method relative to other matched filter techniques.

Strengths

• Data originates from the Planck satellite mission, a major space observatory.
• Provides results from three independent detection pipelines (MMF1, MMF3, PwS) for expert assessment.
• Includes external validation information such as cluster identification and 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.
• Data may reflect temporal bias inherent to the specific Planck observation period.
