Notes.

(a)

Mean date.

(b)

Line area in main beam brightness temperature scale measured on WBS spectra, except for HF (HRS spectrum) and H2O lines (median of WBS and HRS retrievals). Errors correspond to 1-σ statistical noise, and upper limits correspond to 3-σ. Calibration errors (at most 5%) are not included.

(c)

Assuming Tkin = 60 K for 103P/Hartley 2, and a variable temperature law for C/2009 P1 (Garradd) (see text).

(d)

Frequency of the main hyperfine component F1(5/2−3/2).

(e)

Weighted average of the 3 hyperfine components.

(f)

Line area measured in the HRS spectrum. The line area measured in the WBS spectrum is 51 ± 11 mK, but the retrieval is somewhat baseline-dependent.

(g)

Determined by fitting the whole map; the error reflects the dispersion of the retrievals at different points in the map.

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.
