Data set description 1.1. Data set overview The data set contains images acquired with the AMIE camera aboard the SMART1 spacecraft. The AMIE CCD of 1024 x 1024 pixels is divided into eight regions covered by five different filters (one of them being just no filter). The size of the different regions varies from 256 x 256 to 512 x 512 pixel. The individual data products i.e., the image files contained in subdirectories of the `DATA directory each contain one filter image. The CCD has almost always been read out completely. Only in orbit 321, other modes where the CCD is read out only partly have been tested. Files for filters not read out have been padded with dummy values. For each image acquisition, files for all eight filter images are present in the dataset. Even if the CCD has been read out completely, the used exposure time may only be appropriate for some of the filters, cf. 2.3. For details on the arrangement and properties of the filters see the EAICD in the `DOCUMENT directory. Basic geometry and illumination information is provided in the label of each image. More comprehensive information is provided in the table `GEO_MOON.LBL/`GEO_MOON.TAB in the `INDEX directory. 1.2. Parameters The measured parameter is brightness. The unit is brightness on a relative scale which is the same for all images. 1.3. Processing The input data were the raw AMIE data which are provided as another dataset of the same collection. The raw images have been dark trunca [truncated!, Please see actual data for full text]

1 数据集概述
1.1 数据集概览
本数据集收录了SMART1航天器上AMIE相机的成像数据。AMIE相机配备的1024 x 1024像素CCD被划分为八个区域，分别由五种不同的滤光片覆盖（其中一种为无滤光片）。不同区域的大小介于256 x 256至512 x 512像素之间。各个独立的数据产品，即包含于`DATA目录`子目录中的图像文件，各包含一幅滤光片图像。CCD几乎总是被完全读取。仅在轨道321以及其他CCD只部分读取的测试模式中，对未读取的滤光片文件进行了填充。数据集中，对于每次图像获取，均包含八个滤光片图像的文件。即使CCD已被完全读取，所使用的曝光时间也可能仅适用于部分滤光片，详见表2.3。关于滤光片的排列和特性，请参阅`DOCUMENT目录`中的EAICD。每张图像的标签提供了基本几何和照明信息。更详细的信息可在`INDEX目录`中的`GEO_MOON.LBL/GEO_MOON.TAB`表中找到。
1.2 参数
测量的参数为亮度，单位为相对亮度尺度，适用于所有图像。
1.3 处理
输入数据为原始的AMIE数据，作为同一系列数据集的一部分提供。原始图像经过暗场截断处理[截断！，请参考实际数据获取完整内容]。
