Notes.

a

The Ca+ signal is highly asymmetric (see Fig. G.1), therefore the Gaussian fit may not be accurate.

b

The H signal corresponds to the direct fit of the observed Hα line in the planetary transmitted spectrum and not to a CCF, as was done with remaining species.

c

The S/N columns correspond to the significance of the detection. This significance was computed as the ratio of the fit amplitude to the standard deviation of the binned adjacent continuum (with the binning width equal to the fit FWHM).

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.
