IXPE Master Catalog: NASA X-ray Polarimetry Observations and Targets

The IXPE Master Catalog is a NASA HEASARC table listing targets and observations from the Imaging X-ray Polarimetry Explorer (IXPE) mission, launched in late 2021. It contains planned future targets and processed, validated observations, with data availability determined by a public date parameter. The catalog is generated by the IXPE Team and updated regularly.

Use Cases

• Identifying available X-ray polarization data for specific astronomical targets based on the public date parameter.
• Planning future observational studies by reviewing the catalog of unobserved targets.
• Analyzing mission coverage and target selection trends for compact objects and extended sources mentioned in the description.

Strengths

• Data is generated and updated regularly by the official IXPE Team.
• Includes a clear public_date parameter to determine data availability status.

Limitations

• Row count and dataset scale are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
