Notes. Best-fit values of the compositional analysis fit on correlated fluxes in the N band employing the DHS opacity model and only including detected dust species as given in Table A.2. Any nondetection of a certain dust species is indicated by gray 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.
