Photometry of outer Solar System objects from the Dark Energy Survey I: photometric methods, light curve distributions and trans-Neptunian binaries - data release

This repository contains the full data release for the 814 outer Solar System objects found in the Dark Energy Survey. A full description of the object search is described in Bernardinelli et al (2022), and a full description of the photometric processing is described in Bernardinelli et al (2023). If you use these files, we ask you to cite the corresponding papers. The FITS table `y6_des_tnos_color.fits` contains both the orbital elements and the colors for each object. The full description of the orbital element information is given in Table 3 of Bernardinelli et al (2022). In addition to these, the table also includes the mean absolute magnitudes in each band, as well as mean \((g-r, r-i, r-z)\) colors and their corresponding covariance matrix, and the 68% confidence interval for the lightcurve amplitude. Inside the `fluxes` directory, the complete photometric record for each object is included in a `hdf5` file (for each object), and the MCMC chains for their fluxes and LCAs. The three Jupyter Notebooks included in the `notebooks` directory explains the columns and how to use these files to reproduce the results of the paper. Inside this directory there are also additional files needed to reproduce the code. The `binary` directory has the MCMC chains for their mutual orbits (in `.npy` files), as well as the astrometric and photometric record for the binary measurements. Another `README` file is included in that directory with a detailed explanation.本仓库包含暗能量巡天（Dark Energy Survey）中发现的814个外太阳系天体的完整公开数据。天体搜索流程的完整说明详见Bernardinelli等人（2022）的研究论文，测光处理流程的完整描述则刊载于Bernardinelli等人（2023）的相关工作。若使用本数据集，请务必引用对应文献。 柔性图像传输格式（FITS）表格`y6_des_tnos_color.fits`收录了所有天体的轨道参数与颜色信息，其中轨道参数信息的完整说明见Bernardinelli等人（2022）的表3。该表格还额外包含各波段的平均绝对星等、平均(g-r, r-i, r-z)颜色及其对应的协方差矩阵，以及光变振幅的68%置信区间。 在`fluxes`目录下，每个天体的完整测光记录以单独的hdf5（Hierarchical Data Format Version 5）文件存储，同时还包含对应测光流量与光变振幅的马尔可夫链蒙特卡洛（Markov Chain Monte Carlo, MCMC）采样链。 `notebooks`目录中包含三份Jupyter Notebook，用于解释各数据列的含义，并指导用户如何使用这些文件复现论文中的研究结果。该目录下还附带了复现代码所需的全部辅助文件。 `binary`目录存储了双星系统相互轨道的MCMC采样链（存储为`.npy`文件），以及双星系统测量得到的天体测量与测光记录。该目录下另有一份`README`文件，提供了详细的使用说明。
