Notes. The reference axes are defined by the segmented mirror orientation which is actually rotated compared to the northeast orientation. The uncorrected estimates do not take the rotation of the image plane and the scaling factor into account, while the corrected ones are the final estimates. Horizontal lines separate the three observing runs considered here.

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.
