SPT-3G and EHT receivers on the SPT
收藏资源简介:
该数据集由南极望远镜(SPT)上的SPT-3G和EHT接收器的历史天文观测数据组成,主要用于训练机器学习模型以提高望远镜的指向精度。数据集包含了在极端天气条件下观测的天文源数据,用于校正望远镜的方位和仰角误差。数据集的创建过程涉及对望远镜结构变形的分析,并结合当前天气条件进行动态校正。该数据集的应用领域主要集中在提高望远镜在参与事件视界望远镜(EHT)观测活动中的指向精度,以解决在极端天气条件下望远镜指向误差的问题。
This dataset comprises historical astronomical observation data collected by the SPT-3G and EHT receivers mounted on the South Pole Telescope (SPT). Its primary purpose is to train machine learning models to enhance the pointing accuracy of telescopes. The dataset includes astronomical source data obtained under extreme weather conditions, which is utilized to calibrate the azimuth and elevation errors of the telescope. The development of this dataset entails analysis of the telescope's structural deformation, combined with dynamic calibration that accounts for the prevailing weather conditions during observations. The main application scope of this dataset is to improve the pointing accuracy of telescopes when participating in Event Horizon Telescope (EHT) observation campaigns, thereby addressing the issue of telescope pointing errors under extreme weather conditions.
