Notes.

(a)

Number of lines detected above 3σ. One line may mean a group of transitions of the same molecule blended together.

(b)

Total column density of the molecule.

(c)

Correction factor applied to the column density to account for the contribution of vibrationally or torsionally excited states not included in the partition function.

(d)

Rotational temperature (see Sect. 3.6).

(e)

Source diameter (FWHM) (see Sect. 3.5).

(f)

Velocity offset with respect to the assumed systemic velocity of the source: 74 km s-1 for Sgr B2(N2) and Sgr B2(N3), 64 km s-1 for Sgr B2(N4), and 60 km s-1, for Sgr B2(N5) (see Sect. 3.7).

(g)

Linewidth (FWHM) (see Sect. 3.7).

(*)

Sgr B2(N2)’s parameters are taken from Belloche et al. (2016), Müller et al. (2016), Belloche et al. (2017).

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.
