Notes. Five data points determined with FEROS are not listed here and were not used for further analysis due to high error bars caused by bad weather conditions. The Coralie RV uncertainties listed here are known to be underestimated. Updated estimates are available, but we list here the values we used in the analysis. We note that in any case a jitter is included in the analysis to account for any additional scatter to what is implied by the uncertainties, see Sect. 3.3 (cf. Table 5).
