Notes. The coordinates of the eFEDS source are equatorial, with σRADec, eFEDS being the 1σ X-ray positional uncertainty. The net counts and errors are obtained via photon-mode PSF fitting (Brunner et al. 2022). Sep. eRO/LS8 measures the separation between the centroid of the eFEDS X-ray source and the position of the LS8 counterpart. Sep. QSO/LS8 corresponds to the separation between the quasar optical position and the LS8 counterpart.
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.
