Transmission spectrum models for the atmosphere with haze for the four different cases where C/O = 0.5 (green line; same as the green line in Figure 5), 1 (orange line), 10 (red line), and 1000 (purple line). The transmission spectrum for the atmosphere without haze for the case of C/O = 0.5 is also plotted (black line; same as the black line in Figure 5). As in Figure 5, the horizontal dotted lines represent the transit depths corresponding to pressure levels from 1 × 10⁻⁷ bar to 1 bar for the atmosphere in the case of C/O = 0.5. Note that the transmission spectrum models are smoothed for clarity.
