Gas depletion timescales (left) and gas-to-stellar mass ratios (right) of cluster galaxies relative to the predicted gas properties as a function of stellar mass (top) and of SFR (bottom). The predicted properties are estimated for each individual source given its redshift and stellar mass assuming the scaling relations derived for field galaxies by Liu et al. (2019). Symbols are as in Fig. 6. The solid black line represents the Liu et al. (2019) scaling relation for τ_depl and μ_gas = M_gas/M_star with a scatter of 0.3 dex (grey shaded regions). About half of the CO-emitters in this work is characterized by higher gas-to-stellar mass ratios, which is also seen in the other cluster samples. On the other hand, most of the galaxies in G073 have depletion times consistent with the field.
