Notes. Ratios of mass estimates and carbon abundance, XCI, for the different molecular gas mass estimates from CO.

(a)

For XCI = 3 × 10−5, and αCO, ULIRG = 0.8 M / [K km s−1 pc2].

(b)

Using the average luminosity ratios of the GEMS, and (C18) to extrapolate to .

(c)

CO(1–0) is taken from Harrington et al. (2018), for αCO, ULIRG = 0.8 M / [K km s−1 pc2].
