Notes. Columns are: number of individual spectra observed, ⟨S/N⟩ average signal-to-noise ratio at 550 nm of those spectra, number of measurements obtained after binning the data over 1 h, ΔT the time span of the observations, σRV the rms value of the RV set and ⟨ εRV ⟩ the mean RV photon-noise + calibration error. (a)Star already known as a planet host for which we give here an updated orbit including HARPS observations.
