Notes. The first column gives the name of the field, the four next columns give the mean FWHM and rms of the FWHM within the field in the different bands, and the four last columns show the surface brightness corresponding to 1σ S/N per pixel for a given field in the different photometric bands.

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.
