Orbital solution of HD 206267Aa computed from our RV data assuming a period of 3.710534 days, compared to the orbital solutions proposed by Stickland (1995) and Burkholder et al. (1997), and a solution obtained by combining our RVs with those measured by these authors.

Notes. The notations have the same meaning as in Table 4. All error bars indicate 1σ uncertainties. The “(f)” in the orbital solution derived by Burkholder et al. (1997) stands for values adopted by these authors from the previous determination of Stickland (1995).
