Notes. Given are the object names, their Gaia ID, the number of photons detected in S45, the eROSITA X-ray coordinates, the separation between the Gaia and the eROSITA coordinates in arcsec and normalized to 1σ of the X-ray positional uncertainty, the distance (in pc), and information pertaining to whether the object was known before as an X-ray source and, if available, which subtype was assigned. (1) IGR J16194-2810 is considered being a Symbiotic X-ray binary, not a WD accreting object (e.g. Bozzo et al. 2024); (2) SWIFTJ171951.7-300206 is reclassified here as a likely X-ray active nearby star.
