该数据是安装在嫦娥三号着陆器底部的降落相机在着陆过程中获取的着陆区周边月面影像数据。2A级的降落相机数据进行了相对辐射定标。数据采用PDS 3（Planetary Data System）格式，包含数据标签（数据的描述信息）和数据实体两部分。This dataset comprises lunar surface imagery around the landing zone captured by the descent camera mounted at the bottom of the Chang'e-3 lander during the landing process. The Level 2A descent camera data has undergone relative radiometric calibration. The data is stored in the PDS 3 (Planetary Data System) format, which includes two components: the data label (descriptive information of the dataset) and the data entity.
