Close-up view of Fig. 9. Upper panel: close-up view of the density profiles. Various profiles derived from the RSS occultation are shown in green. The dashed line is the profile retrieved by Tyler et al. (1989) using a polynomial extrapolation B₁ to correct for the RSS phase instability. The thin solid line is the profile retrieved by G95 using the polynomial extrapolation B₂. The dotted line is the same by G95, but using the polynomial extrapolation B₃. The thick solid line is the best model of G95, based on the B₂ profile. Lower panel: same for the pressure profiles.
