Notes.

Columns: (1) Filter identifier. (2) Number of exposures included in the final mosaic. (3) Total exposure time. (4) Median surface brightness limiting magnitude (3σ measured on 10 × 10 arcsec2 boxes) for the ABYSS mosaics. (5) Median surface brightness limiting magnitude for the XDF mosaics, measured in the same way. (6) Median surface brightness limiting magnitude for the HUDF12 mosaics, measured in the same way. The surface brightness limits shown here refer to the pixel noise of the images and do not account for systematic effects.

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.
