Notes. The table gives the HJDs of the observations, the corresponding phases calculated using Eqs. (1) and (2) from Sect. 3.2, respectively, and the measured signal-to-noise (S/N) ratio of the spectra, the wavelength region (Δλ), the heliocentric radial velocity values with their errors and the observatory.
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.
