Same as Figure 8 but using Mmol and tdep derived via the B13 (left), SL24 (middle), and T24* (right) αCO prescriptions. The best-fit slopes for quenched galaxies (red dashed lines) are −0.49, −0.48, and −0.41 for B13, SL24, and T24*, respectively. The qualitative results remain the same as using a constant αCO, as the αCO variation within and among prescriptions is small compared to the orders-of-magnitude span in tdep, and there is no systematic αCO dependence on ΔSFMS.
