Equal to the Tdust as in Table D.1 of Buchbender et al. (2013).


Calculated from I(13CO(1–0)), Tex and 12C/13C = 60.


Estimated from LVG analysis of CO(1–0) and CO(2–1) intensities, with Tdust as Tkin and N(CO) as inputs.


Estimated using n derived from I(CO(1–0)) and I(CO(2–1)) using LVG model, Tex = 91 K and I([C ii]) in Tables 2 and 3 in Eq. (2).


Estimated using N(H2) = 2.2 × 1020I(CO(2–1)) (Braine et al. 2010).


See Tables 2 and 3.
