Those discoveries were made with the CORALIE Echelle spectrograph mounted on the 1.2-m Euler Swiss telescope located at La Silla Observatory, Chile. The planetary system orbiting the nearby G9 dwarf HD147018 is composed of an eccentric inner planet (e=0.47) with twice the mass of Jupiter (2.1MJup) and with an orbital period of 44.24-days. The outer planet is even more massive (6.6MJup) with a slightly eccentric orbit (e=0.13) and a period of 1008-days. The planet orbiting HD171238 has a minimum mass of 2.6MJup, a period of 1523-days and an eccentricity of 0.40. It orbits a G8 dwarfs at 2.5AU. The last planet, HD204313 b, is a 4.0 MJup-planet with a period of 5.3-years and has a low eccentricity (e=0.13). It orbits a G5 dwarfs at 3.1AU. The three parent stars are metal rich, which further strengthened the case that massive planets tend to form around metal rich stars. Description: We present here radial-velocity measurements for 3 low mass stars: HD 147018, HD 171238 and HD204313. These radial velocities were obtained using the CORALIE echelle spectrograph mounted on the 1.2-m Euler Swiss telescope at the ESO-La Silla Observatory (Chile).

Note (1): The CORALIE Echelle spectrograph was upgraded in July 2007 which affected the instrument zero point. We decided to refer to the original CORALIE as CORALIE-98 and to the upgraded one as CORALIE-07. When using both set of data, the instrumental zero point should be adjusted. Note (2): Instrument used as follows: C98 = CORALIE-98 C07 = CORALIE-07
