Notes. For data obtained in 2009, we first provide information about the NARVAL and ESPaDOnS runs taken separately, then about the two subsets merged together. The last line is for the combination of all available data.

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.
