Notes. For each observation, we provide the epoch, the exposure time, the airmass, the distance to the Earth Δ and to the Sun r, the phase angle α, the angular diameter Da of Cybele, and the sub–Earth point longitude λsubE and latitude βsubE. The total exposure time of 240 s corresponds to 1.1% of the rotation period or 4° in the rotation phase.

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.
