a Unless otherwise indicated, the level energies and line parameters (λlu, Aul, flu) were collected from the NIST database (Kramida et al. (2023)). The uncertainties are typically of the order of 10%.

b Line parameters obtained from Boissé & Bergeron (2019).

c Line parameters obtained from Bergeson & Lawler (1993).

d The optical depths of the 2594.50 Å Mn II and 2594.50 Å Fe II lines were added up together in the fits, the two lines being separated by 800 m/s only.

e The two Cr II lines at 2677.95 Å were considered as a single line, with an effective gf-value of 3.27.

f Line parameters obtained from Nilsson et al. (2006).

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.
