STONKS - Multi-mission X-ray catalog

This catalog contains the cross-correlation between XMM-Newton, Chandra, Swift, ROSAT and early eROSITA catalogs, as well as pre-computed XMM upper limits and an estimate of the long-term variability. OM, UVOT, Simbad and GLADE+ matches are also added for convenience. It is used in the STONKS quasi-real time XMM transient detection system (Quintin et al. submitted)

This is a summary table, and the detection-wise information is not available directly here. One can however directly use the variability estimate.

This catalog will be updated and maintained with new data releases of individual X-ray catalogs and the eROSITA data release.
