Notes. Symmetric 68 per cent confidence intervals for one parameter of interest, the value at the maximum likelihood is given in parentheses. The parameters RVA, RVB, σA and σB represent the mean and the standard deviation of the normal distributions describing the intrinsic RV distributions of the single stars in population A and B. The parameter fA is the fraction of stars belonging to population A, while ln Lmax is the maximum log-likelihood of the fits.
