Notes.Details of the spectroscopic data used in this work. The UVES and UES stars are all planet hosts. Three of the UVES stars were observed with a slit of 0.3″ providing a resolving power λ/δλ ~ 110 000.


Total number of stars including those with and without known planets.


Mean signal-to-noise ratio, at λ = 6070 Å, of the spectroscopic data used in this work.


Standard deviation from the mean signal-to-noise ratio.


Signal-to-noise range of the spectroscopic data.
