Notes. Column 1 gives the instrument used (ESPaDOnS data are identified by the letter E followed by the identification number), Col. 2 the Modified Julian Date at mid-exposure, Col. 3 the exposure time, Col. 4 the measured longitudinal field ⟨ Bz ⟩ with its uncertainty, and Col. 5 the mean field modulus in kG (which has a typical estimated uncertainty of 10 kG), and Col. 6 the measured Hα line core EW Wλ. ⟨ | B | ⟩ values for UVES spectra are from Koester et al. (2009).

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.
