Confidence contours for the best-fit parameters obtained from the adjustment of the full set of 143 RV data with Eqs. (10) and (11). The best-fit solutions for the primary, secondary, and equivalent RVs are shown by the red, green, and blue filled dots. The corresponding 1σ and 90% confidence levels are shown by the red and magenta, green and yellow, and blue and cyan contours for the primary, secondary, and equivalent RVs, respectively.
