Comparison between synthetic profiles without considering the O2 transmittance (black) and after applying it (blue). The grey line indicates the transmittance spectra at 35 km for the reference date 2017 June 15; these spectra are normalized and share the same ordinate axis with the intensity. Each row represents a selected time corresponding to different Sun positions over the horizon; α = 0 is the zenith. Columns, from left to right, represent the Stokes I, Q, U, V parameters.
