Notes. The astrometric measurements are derived from SPHERE/IRDIS broadband H measurements (left and right parts), in terms of RA/Dec (Cols. 3–4) and in polar coordinates (Cols. 5–6). In addition, we list the derived optimal number of principal component nPC (Col. 2), as well as the statistical error bars (Cols. 7–8) and the speckle noise error bars (Cols. 9–10), both in polar coordinates.

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.
