Radial velocity measurements of HD 69830

Measurements of the radial velocity of the star HD 69830 obtained by HARPS on the ESO 3.6m telescope at La Silla as a function of time, from November 2004 till February 2005 (a) and from mid-October 2005 till February 2006 (b). The two innermost planets are clearly revealed, while the presence of the third one becomes clear when removing the signal of the inner planets and binning the data points (one per observing run), as shown in (c). The lower parts of (a) and (b) show the residuals from the best fit indicated by the solid line.
