Notes. The contrasts and gain in the coronagraphic images with CLC between open and closed loop (OL and CL) are given at different angular separations. The contrast was computed in average and standard deviation in the coronagraphic image over an annular region with a width 1λ/D centered at the considered separation.
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.
