Fig. 9


Effect of coma (70 nm rms) on the QACITS model. On the left, the image shows the shape obtained when the star image is perfectly centered on the vortex mask, and the image below is the color-coded representation of the measured differential intensity in inner and outer regions of the image to emphasize the visual comparison of the asymmetry in both regions (the flux gradient in each area has an amplitude equal to the measured differential intensity).

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.
