Transmission spectrum models for the atmosphere with haze for two different values of the material density, 1.0 g cm⁻³ (green line; same as the green line in Figure 5) and 1.4 g cm⁻³ (orange line). The transmission spectrum for the atmosphere without haze 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 × 10⁻⁶ bar to 1 bar. Note that the transmission spectrum models are smoothed for clarity.
