Comparison of the haze models to the HST spectrum of HD 86226 c. (Left) Goodness of fit for the parameter space (metallicity and haze formation efficiency) explored using the haze models. (Right) Spectrum models for hazy (maximum 100% haze formation efficiency; solid lines) and clear (dotted lines) atmospheres across the explored metallicity grid (1, 3, 10, 30, 100, 300, and 1000× solar). We note that in most metallicity cases, the solid and dotted lines overlap due to the negligible effect of haze.
