INTEGRAL IBIS 17-Year Hard X-Ray Survey

Part of the [Astronomy Datasets](https://huggingface.co/collections/juliensimon/astronomy-datasets-69c24caf2f17e36128946743) collection on Hugging Face.

The INTEGRAL IBIS hard X-ray survey catalog from 17 years of observations with the IBIS coded-mask telescope aboard ESA's INTEGRAL satellite. Contains 929 hard X-ray sources detected in the 17--290 keV energy range across 24 source types, with multi-band flux measurements in 8 energy sub-bands.

Dataset description

This catalog (Krivonos et al. 2022, MNRAS 510, 4796) presents the deepest all-sky survey in the hard X-ray band to date. Sources were detected using the IBIS/ISGRI detector over 17 years of INTEGRAL observations (2003--2020). The catalog provides flux measurements in 8 energy sub-bands spanning 17--290 keV, plus source classifications, redshifts, and transient/extended flags.
