Notes. The second column, labeled Ba, lists whether the star is considered as a mild (m) or strong (s) barium star. Assignment shifts (based on the abundances; see text) are indicated by an arrow. For completeness, the other columns list the component masses and orbital elements. Possibly inaccurate masses for the two stars with orbital periods close to 1 yr are listed in italics (see text).
