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.

摘自自述文件(README): 本数据集关联Saunders等人(2023,PSJ)与Saunders等人(2024,PSJ)的研究成果,以下为其数据产品的组织架构: /forward_modeling_results.csv —— 存储旅行者2号(Voyager 2)剖面与观测恒星掩星光变曲线的各项对比的安德森-Darling检验(Anderson-Darling test)值与临界值。研究人员将旅行者2号剖面正向建模为恒星掩星光变曲线,以便通过安德森-Darling正态性检验,与地面观测的恒星掩星剖面进行直接对比。文中提供了临界值,详细说明参见Saunders等(2023)第3节与Saunders等(2024)第2节。 /original_occultation_profiles/ —— 此前已发表的地面恒星掩星大气剖面数据。这些数据通过已发表论文中的数据提取软件获取,各数据来源的引用信息如下: /original_occultation_profiles/1977* —— Elliot等人(1979) /original_occultation_profiles/1981* —— French等人(1983) /original_occultation_profiles/1982-04* —— Sicardy等人(1985) /original_occultation_profiles/1982-05* —— French等人(1987) /original_occultation_profiles/1983* —— Elliot等人(1987) /reprocessed_occultation_profiles/ —— 对26份掩星剖面进行重新处理后得到的全部大气剖面数据。 /reprocessed_occultation_profiles/profiles/ —— 仅包含大气剖面数据。 /reprocessed_occultation_profiles/profiles/* —— 每份独立剖面,保留原始垂直分辨率。各列含义如下:半径[km](以天王星中心为原点)、温度[K]、压强[微巴]、数密度[m^-3]、折射率、尺度高度[km](压强尺度高度H = kT/mg)、y[km](观测者与掩星连线相对于天王星中心的交会距离,详细说明参见Saunders等(2023))。列标题中已标注各物理量的单位。 /reprocessed_occultation_profiles/errors/ —— 仅包含大气剖面的误差数据。 /reprocessed_occultation_profiles/errors/* —— 每份独立剖面的1σ误差。 /atmospheric_models/ —— 一维大气模型产品,详细说明参见Saunders等(2024)第5节。 /atmospheric_models/model_parameters/model_constants —— 模型中使用的常量取值,参见Saunders等(2024)表3。 /atmospheric_models/model_parameters/model_parameters —— 模型参数的取值与不确定度,参见Saunders等(2024)表3。 /atmospheric_models/model_profiles/* —— Saunders等(2024)附录C中给出的9种模型的剖面数据。其中,“平均”剖面拟合自26份重新处理后的恒星掩星剖面的平均值;“冷态”剖面拟合自重新处理后的掩星剖面的下限;“暖态”剖面拟合自重新处理后的掩星剖面的上限;“最优拟合”剖面为最优拟合模型结果;“下限”剖面为生成剖面族的下限,用于表征不确定度范围;“上限”剖面为生成剖面族的上限。更多信息参见Saunders等(2024)的表3与附录C。列标题中已标注各物理量的单位。
