Notes. 

(†)

A second companion is probably present in the system (see Sect. 4.1). The orbital parameters for HD 22781 b might therefore change slightly once the two-Keplerian model is used.

(a)

Including wavelength calibration error and 3 m s-1 of systematic error.

(b)

99.7%-confidence interval.

(c)

Systemic radial velocity of the SOPHIE data. The values obtained for the other instruments are 0.1587  ±  0.0082 km s-1, 0.1352  ±  0.083 km s-1, and 0.045  ±  0.011, for the McD, TLS, and Lick data, respectively.

(d)

Dispersion for the SOPHIE data. The values for other data sets are 13 m s-1, 20 m s-1, and 16 m s-1, for the McD, TLS, and Lick data, respectively.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
