Notes. The significance of the detection is given as a signal-to-noise ratio, expressed as a number of σ, for the combined χ2 and the two individual χ2 analyses. The best-fit angular separation, position angle and contrast are given, using both positive and negative contrasts as explained in Sect. 3.3. The last two columns give the upper limit on the contrast of companions in case of non detections, for completeness levels of 50% and 90% of the search region (except for the stars for which circumstellar emission was detected).
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.
