(a)

The equivalent full width at half maximum (FWHM) of the maps. For the SPIRE FTS, the number is given as the width of a 2D Gaussian approximation to the beam profile.

(b)

Integrated luminosity at the resolution of 42′′ over the un-masked pixels in Fig. 1.

(c)

Observation done at the Swedish-ESO Submillimetre Telescope (SEST), see Lundgren et al. (2004) for details.

(d)

Observation done at the Atacama Submillimeter Telescope Experiment (ASTE), see Muraoka et al. (2009) for details.

(e)

S/N< 1, the value given is the 1σ upper limit.

(f)

The [NII] 205 μm luminosity is calculated from the map at a spatial resolution of 22′′.

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.
