The precise radial velocities presented in this paper are available in electronic form at the CDS via anonymous ftp to cdsarc.u-strasbg.fr (130.79.128.5) or via http://cdsweb.u-strasbg.fr/cgi-bin/qcat?J/A+A/415/391, except for the multi-planet systems that will appear in a future paper describing their dynamical evolutions, taking planet-planet interaction into account.

... papers

Another dedicated series has also been started for close binaries requiring a 2-dimensional correlation analysis for radial-velocity estimates. The method has already revealed a 2.5- $M_{\rm Jup}$ planet orbiting the primary (Zucker et al. 2003b) and a 19- $M_{\rm Jup}$ brown dwarf orbiting the secondary (Zucker et al. 2003a) of the HD 41004 close visual binary system.

...luminosities

When not available from the spectroscopic study, a photometric $T_{\rm eff}$ (following Flower 1996, not given in Table 1) is used to derive an indicative star luminosity.

... paper

The CORALIE numerical mask used in the cross correlation for the velocity estimate was built from a K0-dwarf spectrum. For much earlier spectral-type stars (typically $\leq$ G1), the mismatch between the stellar spectrum and the template is enhanced by the weighted scheme and no improvement is obtained for the radial-velocity measurements. The usual cross correlation scheme is then used in such cases (Table 2).

... candidates

At the IAU Symp. 202 in Manchester, we announced 6 CORALIE candidates (Mayor et al. 2000; Queloz et al. 2000; Udry et al. 2000b, 5 of them being described in this paper) and 1 further ELODIE candidate (Sivan et al. 2000). The proceedings of the IAU Symp. 202 have not yet appeared. Our 8 contributions to this conference describing the planet and brown-dwarf CORALIE and ELODIE new detections, the metallicity of stars hosting planets, the effect of stellar activity on radial-velocity measurements and a presentation of the new HARPS spectrograph (now running on the ESO 3.6-m at La Silla) are accessible from our Exoplanets web page: http://obswww.unige.ch/Exoplanets/publications.html

... exoplanets

Long-period candidates on low-eccentricity orbits (closer to the giant planets in our solar system) are however more and more often discovered as the time coverage of the radial-velocity surveysincreases.
