用于探索太阳动力学观测站图像中恒星活动对天体测量影响的太阳数据集

本数据集名为‘用于探索太阳动力学观测站图像中恒星活动对天体测量影响的太阳数据集’，由麻省理工学院物理系和卡弗里天体物理学与空间研究所创建。数据集包含2700张太阳图像，这些图像是从NASA的太阳动力学观测站（SDO）获取的，用于研究太阳黑子对天体测量精度的影响。数据集的创建过程涉及图像下载、处理和分析，以计算太阳黑子引起的中心流量与几何中心之间的偏移。该数据集主要用于研究天体测量中的误差源，特别是由恒星活动引起的误差，以提高系外行星探测的准确性。

This dataset is named 'Solar Dataset for Exploring the Impact of Stellar Activity on Astrometry in Solar Dynamics Observatory Images', and was created by the Department of Physics, Massachusetts Institute of Technology and the Kavli Institute for Astrophysics and Space Research. This dataset contains 2700 solar images acquired from NASA's Solar Dynamics Observatory (SDO), which are utilized to study the impact of sunspots on astrometric accuracy. The development of this dataset involves image downloading, processing and analysis to calculate the offset between the centroid flux and the geometric center caused by sunspots. This dataset is mainly used to investigate error sources in astrometry, especially those induced by stellar activity, so as to enhance the accuracy of exoplanet detection.
