Notes. Furthermore, we present the primary K-band magnitudes corrected for the contribution of the CCs (see Eq. (2)). (a) Status is either companion (C), background (B), or ambiguous (A). The latter classification indicates that neither the background nor the companion hypothesis are confirmed by proper motion analysis at the 5σ level. For the ambiguous cases we also present the background probability pB based on our TRILEGAL analysis (Eq. (1)) in the next column. (b) For confirmed background objects, we do not provide masses and effective temperatures because these parameters depend on the distance to the object, which is not known in these cases. For all dubious cases the distances and temperatures are calculated for the case that the object is at the same distance as the primary.
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.
