Transmission spectrum models for the atmosphere with haze for nine different choices of UV irradiation intensity: 10⁵ (red line), 10^2.5 (yellow line), 100, 10, 0.1, 0.01 (all represented by black thin lines), 10^−2.5 (blue line), and 10⁻⁵ (purple line) times the fiducial value (green line; same as the green line in Figure 5). All of the lines except the fiducial one are labeled “UV× n” (n = 10⁵, 10^2.5, 100, 10, 0.1, 0.01, 10^−2.5, 10⁻⁵). The haze-free transmission spectrum for the fiducial UV intensity is also plotted (black line; same as the black line in Figure 5), but can hardly be seen because it overlaps with that for the atmosphere with haze in the case of UV  × 10⁻⁵ (purple line). As in Figure 5, the horizontal dotted lines represent the transit depths corresponding to pressure levels from 1 × 10⁻⁶ bar to 1 bar for the atmosphere in the fiducial UV case. Note that the transmission spectrum models are smoothed for clarity.
