Notes. The last column indicates the significance of the solution that was possible to derive. For the triple systems HD 71827, HD 212735 and BD+212816, only the inner companion b orbit was considered, since the outer companion is not constrained by RVs. The binary system HD 193554 is already solved in the HIPPARCOS double and multiple catalogue. Upper-limits can be calculated only if at least close to the full orbital period is covered by the HIPPARCOS data.
