Notes. 

(a)

Note that in general, only candidates with a projected separation larger than 320 AU were followed-up.

(b)

Background status confirmed by Janson et al. (2011).

(c)

Known brown-dwarf companion redetected in our data (Lowrance et al. 2000).

(d)

Co-motion of the HR 8799 planets has been confirmed by multiple authors (e.g. see Marois et al. 2008b, 2010b; Bowler et al. 2010b; Currie et al. 2011).

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.
