Notes. DIT: detector integration time. Parallactic angle as measured at the start and end of each coronagraphic IRDIS sequence. Minimum and maximum values of the coherence time, airmass, wind speed, and seeing. Plate scales and TN were measured on non-coronagraphic data.
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.
