The column SrcID lists the source ID in the published X-ray source list from Brunner et al. (2022). The X-ray flux in the energy band 0.2 − 2.3 keV is given in units of 10−14 erg cm−2 s−1. The optical magnitude and color are from the legacy survey. A parallax is given, if the source is listed in Gaia DR3. The distance D is rgeo from Bailer-Jones et al. (2021) and the logarithm of the X-ray luminosity (0.2 − 2.3 keV) was calculated using this distance with geometry parameter 4π. The “Type” column gives the likely subtype with following meaning: AMC – AM CVn, CV – not further specified CV, DN – dwarf nova (not further specified), SU – SU UMa type dwarf nova, UG – U Gem type dwarf nova, WZ – WZ Sge type dwarf nova, P – polar. The second to last column lists the orbital period in hours, letters in parenthesis refer to explanations in the foot of the table. In the last column references to original publications are given, the given numbers are expanded below the table. The lower part lists CVs that were not X-ray selected. For those X-ray upper limits from eFEDS are given. a) The period was estimated from outburst parameters (likely recurrence time and outburst magnitude), using relations derived by Levitan et al. (2015); b) Period estimate based on SpT of the donor; c) The parameters (distance, period, luminosity, sub-type) are based on the estimated spectral type of the donor and its brightness using the sequence tabulated by Knigge et al. (2011);(d) The X-ray source is not listed in the main, but is in the supplementary eFEDS X-ray catalog. References: (1) this work, (2) Drake et al. (2014), (3) Breedt et al. (2014), (4) Szkody et al.
