Table A.1.

Known CVs detected in eROSITA DR1 (extract). The full list of 416 CVs is published at the CDS. Given are per object the IAU name from DR1, the CV name and its type (IPs with 4 and 5 stars are labeled IPs, those with 2 and 3 stars are labeled IPcands), the Gaia source ID, the X-ray coordinates (RA and DEC), the separation between the X-ray and the optical (Gaia) coordinates in arcsec, the number of photons collected in DR1 in the energy band 0.2 − 2.3 keV, the logarithm of the derived flux (in erg cm−2 s−1), the Gaia G-band magnitude, the distance (in pc), the logarithm of the derived X-ray luminosity (in erg s−1), the X-ray to optical flux ratio, the absolute magnitude in the G-band, and the Gaia color.
