$^a$ Estimated with an ambient density of 10$^{4}$ cm$^{-3}$. 
$^b$ CO 3--2/6--5 line wing ratio. Ratios are averaged over velocity and distance from the source. See \citet{vanKempen09} for more discussion.
$^c$ CO 4--3/6--5 ratio.
$^d$ Optical depth of 8 inferred for $^{12}$CO 3--2 wings \citep{Hogerheijde98}.
$^e$ See \citet{vanKempen09}.
