Notes. References are provided for those that have previously been identified as DDs, in many cases from the SPY survey. The probability of a false positive, type and mass of the primary M1 is given (see Appendix C). M2 and P are secondary masses and periods determined by follow-up observations.
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.
