Notes. The successive columns signify (1) – comet designation, (2) – epoch, i.e. osculation date, (3) – perihelion time [TT], (4) – perihelion distance, (5) – eccentricity, (6) – argument of perihelion (in degrees), equinox 2000.0, (7) – longitude of the ascending node (in degrees), equinox 2000.0, (8) – inclination (in degrees), equinox 2000.0, (9) – inverse semi-major axis in units of 10-6 au-1.
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.
