Notes.

(a)

Data from Leiden Atomic and Molecular Database (except for [NII] and [OIII], whose data come from Carilli & Walter 2013).

(b)

Critical density (CO data from Walker et al. 2015 and the rest from Tielens 2005). For the CO, [CI], [CII], and [OI] lines, the critical densities are evaluated at the kinetic temperature of 100 K.

(c)

Angular resolution of the original data.

(d)

Median σs in the integrated intensity at 42′′ resolution (σs = statistical 1σ uncertainty).

(e)

Median σf in the integrated intensity at 42′′ resolution (σf = final 1σ uncertainty; statistical and calibration errors added in quadrature).

(f)

Luminosity derived by integrating over all pixels with S/Ns> 5 at 42′′ resolution.

(g)

Except for CO(1–0) at 45′′ resolution.

(h)

For CO(1–0) and CO(3–2), the conversion factors of 1.6 × 10-12 and 4.2 × 10-11 are used to convert K km s-1 into W m-2 sr-1.

(d,e,f)

Different spatial areas are considered for the estimates: ~1.0′ × 1.5′ for the [CII], [OI], and [OIII] transitions and ~2.5′ × 2.5′ for the rest.

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.
