Fig. 2


Comparison between different Rayleigh scattering prescriptions used in the literature. The black solid line is the prescription adopted in this work (Dalgarno & Williams 1962) and recommended by Seager (2010). The red solid line is the prescription adopted in the previous version of the program, based on Karplus (1964). Finally, the red dashed line is the version adopted by Heng (2016), based on Cox (2000). The relative difference between the prescriptions by Dalgarno & Williams (1962) and Karplus (1964; lower panel, solid line) is negligible for wavelengths longer than 3300 Å, of interest for this work. The difference between Dalgarno & Williams (1962) and Cox (2000) is negligible even bluewards.
