Retrieved HO vertical profiles from all spectral windows (blue lines) in the observation performed during orbit 2520, as well as the weighted-averaged profile (orange line). Uncertainties in the averaged profile in panel A are derived from the propagation of errors from each retrieved profile. Uncertainties in panel B are calculated as the weighted standard deviation from all the profiles. Panel C shows the combination of the two previous panels, selecting the larger of the two methods. Altitudes are defined with respect to the Martian ellipsoid.
