Notes. Binaries listed in Table 5 are shown in bold, and candidate binaries listed in Table 6 are shown in italics. RVs are measured from the Paschen series, unless noted as follows: aRVs measured from Ca II λλ8542,8662, bRVs measured from Ca II λλ8912,8927 (see Ritchie et al. 2009b), cRVs measured from the C III λ8664 emission line (see Clark et al. 2011), dRVs measured from He I λ8845. Values presented for 2011 and 2013 FLAMES observations only. For W13, values are given for the more massive absorption-line component (Ritchie et al. 2010).

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.
