Notes. (a)From Müller et al. (2005) and Pickett et al. (1998). (b)Half power Gaussian beam width and average radial pointing offset. On average 9.3–10.0′′ corresponded to 4000–4400 km at the distance of comet 64P and 9.4–16.7′′ corresponded to 5200–9300 km at the distance of 38P.

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.
