INTEGRAL IBIS Hard X-Ray Survey Source Catalog, 2002-2014

Over 11 years of operation from December 2002 to January 2014, the INTEGRAL satellite's IBIS telescope performed an all-sky survey at energies above 100 keV. The resulting catalog contains 132 known X-ray sources, with a statistical sample of 88 sources detected above 5 sigma significance in the 100-150 keV band. The data was compiled by the National Aeronautics and Space Administration (NASA).

Use Cases

• Classifying high-energy celestial objects based on the catalog's breakdown of 28 AGNs, 38 LMXBs, 10 HMXBs, and 12 pulsars.
• Analyzing source variability and detection significance across different time periods, as mentioned for 29 catalogued sources.
• Studying spectral hardness ratios for Galactic and extragalactic sources as presented in the reference paper.
• Investigating population statistics, such as the LMXB longitudinal asymmetry or number-flux relation for non-blazar AGNs.
• Identifying compact object types, such as the 12 black hole candidates and four neutron star binaries noted among LMXBs and HMXBs.

Strengths

• Catalog has 100% purity, as all 132 registered sources are known X-ray emitters.
• Survey spans a long temporal range, utilizing data from over 11 years of INTEGRAL operation.
• Provides high-energy detections, with 25 sources detected in the 150-300 keV band at S/N >= 5 sigma.
• Offers detailed sensitivity metrics, with peak sensitivity of about 2 mCrab and sky coverage down to specific flux limits.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for specific analytical tasks.
• Data formats include BIN and HTML, which may require specialized tools for access and analysis.
