Targets with combined RV data sets. In all panels, RV data from our SOPHIE survey are plotted as black dots, and the yorbit fit we derived from the combined RV data sets (either linear, quadratic, or Keplerian) is overplotted in red. Top left panel: HD 16232 – RV data from Kane et al. (2015) are plotted as blue triangles. Top right panel: HD 162003 – RV data from Endl et al. (2016) are plotted as blue triangles. Bottom left panel: HD 185395 – our ELODIE RV data (Desort et al. 2009)are plotted as blue triangles and RV data from Howard & Fulton (2016) are plotted as orange diamonds. Bottom right panel: HD 199254 – our HARPS RV data (Paper IX) are plotted as blue triangles.
