Notes. The mass function f(m) and the apparent orbital separation a1 sini, which depend on P, e, and K1, are also included. The last column shows the standard deviation of the residuals of the fit. In the upper part of the table, we list the 25 dwarf and subgiant Ba and CH stars that are in SB1 systems. In the bottom part, we include the orbital parameters of the inner and outer orbits of the confirmed triple system, HD 48565 (see Sect. 4.2), and the parameters of the constrained Ba SB2 system, HD 114520 (see Sect. 4.3).
