Notes. We divide our model grid into a ‘cool’ (< 25 kK) and a ‘hot’ (> 25 kK) sections which correspond to different ions. “all” in the models column means that this ion has was included in the hot and cool sections of our grid.

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.
