Notes. For each visit, we list the barycentric Julian date BJD, rotation cycle c and phase ϕ, the total observing time t_exp, the peak S/N in the spectrum, the noise level in the LSD Stokes V profile and the estimated B_ℓ with error bars. The full table is available at the CDS.

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.
