Notes. OBSIDs are the observation identifiers, duration is the total duration of the four AORs (see text), mid-time is the mean UT time, r is the mean heliocentric distance, Δ is the mean Herschel-target distance, and α is the mean phase angle. Each line corresponds to one visit and all three channels were observed at each visit. r, Δ and α are from the JPL Horizons Ephemeris System (Giorgini et al. 1996).

(a)

Observation in the chopped and nodded point-source mode and only at the blue and red channels (Müller et al. 2010).

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.
