Notes.The first column identifies the sequence number of a full set of four subexposures in the given observing period. In case of missing numbers (in 2001), the obtained intermediate spectra (less than four) were used for the radial velocity study. The Barycentric Julian date is given at the centre of the total exposure time (texp). Column 5 lists the quality of the Stokes V spectra, which is expressed as the S/N per 4.5 km s-1 around 550 nm in the raw spectrum, and the relative rms noise level NLSD (per 4.5 km s-1 velocity bin) in the least-squares deconvolved Stokes V spectra. The phase in the radial velocity curve (with phase 0 defined at maximum) has been calculated with the ephemeris given by Pigulski & Boratyn (1992) in Col. 7. The UV (rotational) phase in Col. 8 has been derived from Eq. (3). The measured radial velocity (accuracy: 2.5 km s-1) is given in Col. 9, whereas the velocity shift, which is measured at minimum flux and used before calculating the magnetic field, is given in Col. 10. Columns 11 and 12 give the magnetic field values with their 1σ uncertainties. The last two columns give the computed magnetic values of the diagnostic null (or N) spectrum with their 1σ uncertainties.
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.
