Using the NWAY algorithm (Salvato, M. et al. 2018, MNRAS, 473, 4937), we have crossmatched the set of X-ray sources extracted from the CSC 2.1 production-current database on 14 November 2022 (387k sources) to four catalogs—Gaia DR3, Legacy Survey DR10, PanSTARRS-1, and 2MASS, finding counterparts for 229k CSC 2.1 production current database sources.
