Notes.

(a)

CO[1–0] luminosity assuming an excitation correction of r31 = 0.5. The quoted uncertainty includes the observed uncertainty in the flux measurement and the uncertainty in r31, in quadrature.

(b)

Derived based on DL07 models.

(c)

Average value, between CO, δGD and R-J approach.

(d)

Based on a MBB model with fixed β = 1.8.
