Geometric albedo model results, produced by sampling over the input parameter prior distributions (see Table 3) and assuming chemical equilibrium. The wavelength-dependent albedos were then bandpass-integrated to produce the expected albedos in the TESS (orange) and CKC (blue) band. Not shown are the albedos as a function of T_*, T_planet and pressure, as these show no discernible correlation. We find that the metallicity (log [M/H]) has the largest impact on the geometric albedo and that, from this, the water abundance produces slightly tighter constraints on A_g than sodium. We also see very distinct differences between the CHEOPS and TESS bandpasses.
