File name: figure1_uvis_spectrum.csv Plot the second column (spectral brightness) as a function of the first column (wavelength) to reproduce Figure 1a black spectrum. File name: figure1_maven_spectrum.csv Plot the second column (spectral brightness) as a function of the first column (wavelength) to reproduce Figure 1a red spectrum. File name: figure1_limb profiles.csv Plot the second (CO Cameron brightness), the third (OI 297 brightness) or the fourth (CO2+ UVD brightness) colummn as a function of the first column (altitude) to reproduce the black limb profiles of Figure 1b, 1c and 1d. File name: geometry.csv This data file contains the latitude, longitude, solar longitude and solar zenith angle of the NOMAD observations. Use this file to reproduce the geometry data shown in Figure 2. File name: figure3_uvis_spectrum.csv Plot the second column (spectral brightness) as a function of the first column (wavelength) to reproduce Figure 3 black spectrum. File name: intensities.csv This data file contains the altitude, CO Cameron, CO2+ FDB, OI and CO2+ UVD averaged limb profiles. They can be used to reproduce the limb profiles or the ratios shown in the article. File name: figure9_uvis_spectrum.csv Plot the second column (spectral brightness) as a function of the first column (wavelength) to reproduce Figure 9 black spectrum.
