Notes.

^(a)

The intensities in this table are derived over a velocity range either judged by eye, or fixed using a Gaussian wherever [N ii] spectra could be fit unambiguously, in which case we also list their V_lsr and Δv. The second column numbers the individual components in order of appearance in the band from low to high velocity. Most values are rounded off to one decimal place.

^(b)

V_lsr and Δv from a Gaussian fit.

^(c)

Derived by Goldsmith et al. (2015) from PACS [N ii] 205 μm and 122 μm data.

^(d)

See Sect. 3 and Table 2 for correction for absorption.

^(e)

Blend of two closely spaced lines broadens the fit.

^(f)

Multigaussian fit to three overlapping lines with distinct local maxima.
