Notes. The minimum possible period for the third object is given with the corresponding m sin i and semi-major axis derived when fixing the period at this value. In both cases, the orbit of component 1 was derived assuming the drift. In all cases, we fixed the SOPHIE (or Elodie) and SOPHIE+ relative RV offset to 0 m s−1.
