Notes. Columns are: target name (Col. 1), survey number and X-ray coordinates with their uncertainties (Cols. 2–5), net count rate and detection maximum likelihood in the broad band 0.2–10.0 keV (Cols. 6 and 7), offset between proper motion corrected expected position and eROSITA X-ray source (Col. 8), X-ray, and fractional X-ray luminosity (Cols. 9 and 10). The last two columns refer to the energy band of 0.2–2.0 keV.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
