Notes. Columns give the heliocentric Julian date of observations, the peak S/N per pixel of Stokes V spectra, the S/N achieved in the LSD profiles, and the estimates of the mean longitudinal magnetic field derived from Stokes V and diagnostic null LSD profiles. The final column gives the false alarm probability that the structure in the mean circular polarisation profile can be attributed to random noise. Marginal detection corresponds to FAP < 10-3.

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.
