J/A+A/661/A1, Paper I), 24774 of 27369 have reliable counterparts (90.5%) in the main sample and 231 of 246 sources (93.9%) have counterparts in the hard sample, including 2514 (3) sources for which a second counterpart is equally likely. By means of reliable spectra, Gaia parallaxes, and/or multi-wavelength properties, we have classified the reliable counterparts in both samples into Galactic (2695) and extragalactic sources (22079). For about 340 of the extragalactic sources , we cannot rule out the possibility that they are unresolved clusters or belong to clusters. Inspection of the distributions of the X-ray sources in various optical/IR colour-magnitude spaces reveal a rich variety of diverse classes of objects. The photometric redshifts are most reliable within the KiDS/VIKING area, where deep near-infrared data are also available. Together with the catalogues of primary and secondary counterparts to the main and hard samples of the eFEDS survey, this paper releases their multi-wavelength properties and redshifts. The CTP2 catalog lists the possible additional counterparts for about 2500 sources in the Main catalog.surveysx-ray-sourcesactive-galactic-nucleigalaxy-clustersquasarsx-ray-binary-starscosmologystellar-astronomyhigh-energy-astrophysicsgalactic-and-extragalactic-astronomyobservational-astronomyhttps://dc.g-vo.org/rr/q/lp/custom/CDS.VizieR/J/A+A/661/A3http://doi.org/10.26093/cds/vizier.36610003https://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/661/A32022A&A...661A...3Shttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/661/A3Cone search capability for table J/A+A/661/A3/ctpmain (Counterparts for eROSITA sources in Main catalog of Brunner et al., 2022A&A...611A...1B, Cat.
