Refraction signal strengths as functions of six different refraction parameters. The left panel is the 80-day super-Earth and the right panel is Jupiter. The x-axis is the ratio of the changing parameter to its original value. Red is wavelength, green is temperature, blue is planet mass, cyan is radius, magenta is orbital distance, and yellow is molecular weight (which overlaps with planet mass). The signal is measured over 60 min for the 80-day super-Earth and 600 min for Jupiter because of the different characteristic timescales.
