O₂-O₃ relationship for changing N₂O, along with models from Kozakis et al. (2022) for comparison, for all modeled O₂ mixing ratios. Vertical dashed lines indicate O₂ levels of 100%, 10%, 1%, and 0.1% PAL. All plots share the same y-axis to facilitate comparison between different host stars. The phenomena that causes the peak O₃ value for G0V-, Sun-, and K2V-hosted planets to occur at O₂ levels less than the maximum value modeled (150% PAL O₂) is discussed at length in Kozakis et al. (2022).
