Notes.rh is the heliocentric distance. (a)We include thisvalue to indicate the statistical basis of the individual data points. (b) Of the two redundant micro-channel plate/linear electron detector array (MCP/LEDA) rows, usually the one with the higher count rate was used.

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.
