Notes. It is variable due to the presence of the third (Ab) component. In some cases, also the RV of Ab was measured. If the reference is not provided, the value is taken from the list of Harvey et al. (1987) or Mayer et al. (2010), where more information about RV observations is provided (in their App. A). ( * )Denotes the data that were not included in the fit due to systematic errors (see text).
