嫦娥一号干涉成像谱仪2B级科学数据

国家天文台整编的嫦娥一号干涉成像谱仪2B级数据。该数据是搭载在嫦娥一号卫星上的干涉成像谱仪在约200公里轨道高度上获取的32谱段多光谱（0.48μm~0.96μm）数据，2B级的干涉成像谱仪数据经过了几何粗校正校正，修正由轨道、姿态和仪器本身产生的畸变，计算了每个象元在月球上的地理位置。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。

The Level 2B data of the Interference Imaging Spectrometer (IIM) onboard the Chang'e-1 satellite, compiled by the National Astronomical Observatories, Chinese Academy of Sciences (NAOC). This dataset comprises 32-band multispectral observations (0.48 μm to 0.96 μm) acquired by the IIM at an orbital altitude of approximately 200 km. The Level 2B IIM data has undergone geometric rough correction, which rectifies distortions induced by the satellite's orbit, spacecraft attitude and the instrument itself, and calculates the geographic location of each pixel on the lunar surface. 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.
