Planet-to-star radii ratios versus wavelength. Left: constant radius (solid red line) and three pRT models with clear atmosphere and terminator temperatures of 1449 (dotted orange), 1000 (dash-dotted cyan), and 700 K (dashed blue). Right: pRT model assuming the equilibrium temperature at terminator with a cloud deck (solid grey thick line), shifted and rescaled model to have the continuum baseline and line peaks of the clear atmosphere model (solid grey thin line), and cloud-free model with the same temperature (dotted orange).
