Notes. One Gaussian component was fitted to all spectra at position C. At position E we fitted two Gaussian components to the spectra with a line center velocity of component 1 fixed to 24 km s-1 as derived from the single-component fit to the 13CO(2–1) spectrum. The line parameters for [C II] are additionally calculated from their moments between –30 and 100 km s-1 (numbers in italics).

(a)

Results from calculating the moments of the line.

(b)

To convert from flux density Jy beam-1 km s-1 to brightness temperatures we applied a factor of 4.4 assuming an effective beam size of 5.5′′ (Helfer et al. 2003).

(c)

The line center velocity was set to 24 km s-1 .

(d)

The line center velocity was set to 53 km s-1 .

(e)

The line width was set to 47 km s-1 .
