Notes. The minimum and maximum value registered are tabulated for the wind speed, coherence time, and seeing, while the median registered value is in parentheses. (a)DIMM measured values during the observations. (b)Seeing measured on the image analysis detector (at the pointing location).(c)DIT = detector integration time.
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.
