Notes. φ: pulsation phase, estimated with the ephemeris from Samus et al. (2009). N: number of frames in the cube. FoV: field-of-view. Seeingλ: seeing at the observed wavelength, converted from the one measured in V at the spots of the Shack-Hartmann active optics wavefront sensor. AM: mean airmass. r0,t0: average values of the Fried parameter and coherence time, estimated from the adaptive-optics real time calculator.

All broad-band observations were used with a neutral density filter.

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.
