Notes.

(a)

Taken from The Cologne Database for Molecular Spectroscopy (CMDS) (Müller et al. 2001, 2005; http://www.astro.uni-koeln.de/cdms/).

(b)

Calculated based on Roelfsema et al. (2012) for HIFI/Herschel. Taken from http://www.submm.caltech.edu/cso/receivers/beams.html (calculated FWHM) for CSO data. For non-circular beams an average has been used.

(c)

Line-integrated intensity averaged along the bar at the position of the peak (see text), Tmb scale. For HIFI/Herschel the error on Tmb is about 10% (see Roelfsema et al. 2012). The error given for the CSO data has been calculated (and extrapolated for frequencies >345 GHz) based on the errors on and ηmb given in Mangum (1993).

(d)

Measured spatial offset into the PDR (with position angle 145° east of north) relative to the CSO reference position.

(e)

Measured spatial shift into the PDR (with position angle 145° east of north) relative to the [Cii] peak position.
