Average normalized profiles of CO integrated intensity (I_CO(R)/I_CO(R_e) and I_CO(R)/I_CO(R_80%,CO)) and molecular mass surface density (Σ_mol(R)/Σ_mol(R_e) and Σ_mol(R)/Σ_mol(R_80%,mol)). Blue profiles are for high-C_CO or high-C_mol galaxies, while red profiles are for low-C_CO or low-C_mol galaxies. The shaded regions mark the standard deviation in y-axis value for a given normalized radius.
