Notes. Column headers: Mode, instrumental settings of imaging (Image) and imaging-polarimetry (Impol) observations; N, number of exposures; Exptime, individual exposure time in seconds; rH and Δ, median heliocentric and geocentric distances, respectively, in au; α, median phase angle (angle of Sun–comet–observer) in degrees; and ν, median true anomaly in degrees. We referred to the web-based JPL Horizons system (http://ssd.jpl.nasa.gov/?horizons) to obtain the ephemerides (as of 2019 Aug 28).
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.
