XRISM Master Catalog: X-Ray Satellite Observations

A catalog of observations from the X-Ray Imaging and Spectroscopy Mission (XRISM), launched on 2023-09-06. The table lists completed, accepted, and planned observations for the mission's two instruments, Resolve and Xtend, and is updated automatically by the NASA HEASARC.

Use Cases

• Planning observational campaigns based on the catalog of accepted and planned targets.
• Analyzing X-ray spectral data from the Resolve instrument's 1.7-12 keV bandpass.
• Studying wide-field X-ray imaging data from the Xtend instrument's 38x38 arcmin field of view.
• Tracking the operational timeline and target list for the XRISM satellite mission.

Strengths

• Data is supplied by the authoritative XRISM Science Data Center at NASA/GSFC.
• Catalog includes planned observations and pre-approved targets for time-critical events.
• Updated automatically on a regular basis, with a last recorded update in March 2026.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The Resolve instrument is currently operating with a limited bandpass (1.7-12 keV) due to a closed gate valve.
