Notes. The results on these last 4 objects were not published before. The first line for each target contains the 4 subsequent measurements (twice the blue band, twice the green band, and four times the red band) for the first visit, the second line contains the measurements of the second visit, after the target has moved by a few beams. The identification number of the observation is given, followed by the duration and mid-time of the exposure. We also present the heliocentric distance (r), geocentric distance (Δ), and phase angle (α) of the observation.

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.
