Description

From the README file:

Organization of data products connected to Saunders et al. (2023, PSJ) and Saunders et al. (2024, PSJ).

/forward_modeling_results.csv -- Anderson-Darling test values and critical values for each comparison between Voyager 2 profiles and observed stellar occultation light curves. Voyager 2 profiles were forward modeled into stellar occultation light curves to enable a direct comparison to observed, Earth-based stellar occultation profiles using the Anderson-Darling test of normality. Critical values are provided. See Section 3 of Saunders+23 and Section 2 of Saunders+24.

/original_occultation_profiles/ -- Previously published atmospheric profiles from Earth-based stellar occultations. Data were extracted using a data extraction software on published papers. The citation for each data source is provided below. 
/original_occultation_profiles/1977* -- Elliot et al. (1979)
/original_occultation_profiles/1981* -- French et al. (1983)
/original_occultation_profiles/1982-04* -- Sicardy et al. (1985)
/original_occultation_profiles/1982-05* -- French et al. (1987)
/original_occultation_profiles/1983* -- Elliot et al. (1987)

/reprocessed_occultation_profiles/ -- All atmospheric profiles resulting from reprocessing the 26 occultation profiles.
/reprocessed_occultation_profiles/profiles/ -- Only the atmospheric profiles.
/reprocessed_occultation_profiles/profiles/* -- Each individual profile, in original vertical resolution. Columns: radius [km] (from center of Uranus), temperature [k], pressure [microbar], number density [m^-3], refractivity, scale_height [km] (pressure scale height H = kT/mg), y [km] (close-approach distance of the line connecting the viewer and the occulted star to the center of Uranus, see Saunders+23 for description). Units are provided in column headers.
/reprocessed_occultation_profiles/errors/ -- Only the errors for the atmospheric profiles.
/reprocessed_occultation_profiles/errors/* -- 1-sigma srrors for each individual profile.

/atmospheric_models/ -- One-dimensional atmospheric model products. See Section 5 of Saunders+24.
/atmospheric_models/model_parameters/model_constants -- Values of constants used in the models. See Table 3 of Saunders+24.
/atmospheric_models/model_parameters/model_parameters -- Values and uncertainties of model parameters. See Table 3 of Saunders+24.
/atmospheric_models/model_profiles/* -- Profiles for the 9 models provided in Appendix C of Saunders+24. "Average" profiles are fit to the average of the 26 reprocessed stellar occultations; "cool" profiles are fit to the lower bound of the reprocessed occultations; "warm" profiles are fit to the upper bound of the reprocessed occultations. "Best-fit" profiles are the best fit model results; "lower" profiles are the lower bound of the family of generated profiles, meant to serve as a range of uncertainty; "upper" profiles are the upper bound. See Table 3 and Appendix C in Saunders+24 for more information. Units are provided in column headers.
