Notes. The Julian date, rotational phase, exposure time, stellar effective RV, longitudinal magnetic field, and the S-index are listed. The RV and Beff measurements with SPIRou are obtained from a night average of LSD profiles. Typical uncertainties for NARVAL radial velocities and S-index measures are 30 m s−1 and 0.002, respectively. The RV precision refers to the relative RV, not the absolute RV. There is likely to be a systematic RV shift (larger than the SPIRou RV error bar) between the two instruments.
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.
