SFR vs. M_mol for the ASPECS CO galaxies compared to the z > 1 PHIBSS1/2 CO sources (Tacconi et al. 2013, 2018), represented by blue contours as in Figure 5. The dashed lines represent curves of constant t_dep at 0.1, 1, and 10 Gyr. A fixed conversion factor α_CO = 3.6 (K km s⁻¹ pc²)⁻¹ has been assumed for the ASPECS CO sources. The comparison sample uses a metallicity-based prescription for this parameter. Typical values will range between α_CO = 2–5 (K km s⁻¹ pc²)⁻¹ for the ASPECS CO sources.
