Notes. P is the orbital period and e the eccentricity (from Jorissen et al., in prep.), type is Ba3-5 (giant barium star with strong anomaly), Ba1-2 (giant barium star with mild anomaly), Ba0 (giant barium star with very mild anomaly), Bad (dwarf barium star), sgCH (subgiant CH), and CH. [Fe/H] is the metallicity and “Ref.” the corresponding reference (N/A if not available), ϖ ± σ and source are the parallax ± its error and source (Gaia, Hipparcos or Pourbaix & Jorissen 2000). The following columns contain the effective temperature and luminosity, with their 1σ ranges, for [Fe/H] = 0, [Fe/H] = −0.25, and [Fe/H] = −0.5 dex (see text).
