Repository of the Francesca Manni thesis degree in Astronomy and Astrophysics, 2022/2023. This archive contains the Retrieval data of orbits 1 (North and South pole), 4, 7, 8, and 26 orbits (South pole). The files contain the following parameters: Spectrum number, Name of the analyzed file, Latitude, Longitude, Solar Zenith angle, χ^2, Column density of CH_4, Error on the Column Density of CH_4, Temperature of the CH_4, Error on the Temperature of CH_4, Column Density on H_3^+, Error on the Column Density of H_3^+, Temperature of H_3^+, Error on the Temperature of H_3^+. Read with the program Fortran. The repository contains also the data to plot the images of the orbits 1, 4, 15 (North and South poles), 9 (North pole), 7, 8, 19, 20, 21, 22, 26, 31, and 36 (South pole) orbits and the routines of Spices metakernel. Read with the program Matlab.
