Notes. Nspecz is the number of spectroscopic redshift measurements that pass the quality threshold (applied to columns provided in the originating catalogue). For Simbad, the number of entries is limited to objects lying within 3 arcsec of the optical coordinates of counterparts to eFEDS sources. Some astrophysical objects appear in two or more redshift catalogues.
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.
