Notes.
(a)
The total is taken as the sum of models C, Dl and warm dust, which is what we consider for the final build-up in Sect. 7; although Dh and CB may also alter the line predictions.
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.
