The Infrared Space Observatory data archive

The Infrared Space Observatory (ISO) is designed to provide detailed infrared properties of selected Galactic and extragalactic sources. The sensitivity of the telescopic system is about one thousand times superior to that of the Infrared Astronomical Satellite (IRAS), since the ISO telescope enables integration of infrared flux from a source for several hours. Density waves in the interstellar medium, its role in star formation, the giant planets, asteroids, and comets of the solar system are among the objects of investigation. ISO was operated as an observatory with the majority of its observing time being distributed to the general astronomical community. One of the consequences of this is that the data set is not homogeneous, as would be expected from a survey. The observational data underwent sophisticated data processing, including validation and accuracy analysis. In total, the ISO Data Archive contains about 30,000 standard observations, 120,000 parallel, serendipity and calibration observations and 17,000 engineering measurements. In addition to the observational data products, the archive also contains satellite data, documentation, data of historic aspects and externally derived products, for a total of more than 400 GBytes stored on magnetic disks. The ISO Data Archive is constantly being improved both in contents and functionality throughout the Active Archive Phase, ending in December 2006.

红外空间望远镜（Infrared Space Observatory，简称ISO）旨在提供所选银河系和河外天体的详细红外特性。该望远镜系统的灵敏度约为红外天文卫星（Infrared Astronomical Satellite，简称IRAS）的千倍，因为ISO望远镜能够对天体的红外通量进行数小时的积分。星际介质中的密度波、其在恒星形成中的作用、太阳系中的巨行星、小行星和彗星等均为研究对象。ISO作为一个观测台运行，其大部分观测时间分配给了天文社区。这一结果导致数据集并非同质化，正如预期从一项调查中得到的。观测数据经历了复杂的数据处理，包括验证和精度分析。总计，ISO数据档案包含了大约30,000个标准观测数据、120,000个并行、意外和校准观测数据以及17,000个工程测量数据。除了观测数据产品外，该档案还包含了卫星数据、文档、历史方面的数据以及外部生成的产品，总计超过400 GBytes存储在磁盘中。在活跃档案阶段，ISO数据档案在内容上和功能上不断得到改进，直至2006年12月结束。
