Results of applying the telluric correction on the Stokes (from left to right) I, Q, U, V profiles. Top row: spectra observed at lower airmass m1, i.e. at 12:00 UTC, while bottom row: spectra at larger airmass m2, i.e. 06:00 UTC. Solid lines represent the original profile, the dotted lines display the same profile affected by the O2 absorption, and squares show the results obtained from the method explained in Section 5.
