Notes. Columns 2–4 contain a solution based on the free convergence; Cols 5–7 contain the solution for the fixed mass ratio of 1. All epochs are in RJD = HJD − 2 400 000. Probable elements and their formal error estimates are provided, where Ω is the value of the Roche-model potential used in the WD program, and Lj (j = 1,2) are the relative luminosities of the components in individual photometric passbands. They are normalized so that L1 + L2 = 1. The number of observations represents the sum of RVs of the primary and secondary and a sum of individual observations in all passbands.
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.
