Notes. The uncertainty quoted on the FIES RVs corresponds to the standard deviation of the correlation results from all spectral orders. For the HERMES data, the uncertainty is instead the formal error on the CCF Gaussian fit on 20 orders. A more realistic uncertainty is the long-term error describing the long-term stability of the spectrographs (see text).
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.
