Notes. The columns are: (1) COADD_ID, the unique ID of the source in DES DR2; (2-3) Galaxy position (RA and Dec., respectively) in degrees (J2000); (4) gmag, the g-band magnitude of the source; (5) q, the axis ratio of the source; (6) g-i, the g-i color index of the source; (7) 〈μeff,g〉, the mean effective surface brightness in g-band; (8-9) redshift and effective radius.

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.
