Spectral classifications (from Evans et al. 2015), estimated projected rotational velocity (vesini), typical signal-to-noise ratios (S/N) for the LR02 region (which have been rounded to the nearest multiple of five) and observed ranges of radial velocity variations of the primary, Δvr.

Notes. The SB2 or SB2? classifications have been updated on the basis of the discussion in Sect. 4.1. Also listed are the estimates of the luminosities discussed in Sect. 4.3, apart from the 4 stars that were not analysed using model atmosphere techniques.

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.
