Notes. For each database, the first row gives the total number of comets on elliptic orbits or the flux per Myr for the models + the number of comets on hyperbolic orbits, followed by the semimajor axis corresponding to the mean orbital energy of all non-hyperbolic comets ā. In the whole table, numbers in brackets for the models correspond to the number of data; see the main text for details. For the three q zones, the first line gives the border of each zone, the second line gives the number and the proportion of comets in each zone. The semimajor axis corresponding to the mean orbital energy of the comets in each q zone are on the third line. For the three z zones, the first line gives the border of each zone and the second line the number and proportion of comets in each zone.
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.
