Notes. Visit number, OB identification number, date, and seeing FWHM for the 54 visits we used for this analysis. Visits are listed in chronological order, and the sequence of their IDs in the first column lacks some numbers because these correspond to the eight visits that we excluded from the analysis (see Sect. 3.1). Visit 53 was obtained by the combination of ten exposures, for a total exposure time of 3600 s; for all the remaining visits, five exposures were combined together, and the total exposure time is 1800 s.
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.
