Notes. For the free retrievals, elemental ratios are calculated using the approach from L13, with Z defined here as (C+O+R)/H. Contrary to Figure C.3, the elemental ratios quoted here are normalized to the solar values.

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.
