Top panel: radial velocity curve of LRa01 E1 0286 as observed with Sandiford (blue downward triangles), SOPHIE (light blue upward triangles), HIRES (green circles), HARPS (red squares), and FIES (green diamonds). The solid line represents the best-fit Keplerian orbit to the data (see text for more details). An RV shift was let free to vary in the fit between the five data-sets. The systemic RV of V_γ = 121.603 km s^-1, as derived from the HARPS data-set only, is plotted with a horizontal dotted line. Bottom panel: the RV residuals after subtracting the orbital solution (see the online edition of the journal for a color version of this figure).
