AST-0428465HoggThis project is an international collaboration between computer scientists and astrophysicists to build and operate an astrometry engine to create correct, standards-based astrometric headers for every useful astronomical image ever taken, past and future, in any state of archival disarray. This service product will be developed, tested, and installed at ground-based observatories, providing a standards-based description of the usually non-linear transformation between image coordinates and sky coordinates, with the intent being to have no 'false positives' but maybe the occasional 'no answer'. As the product matures, it will return calibration and band-pass information from standards identified in the image, and future versions may even be able to work without any prior information about approximate scale, location, and orientation. Some subset of trustworthy data will be used to improve the astrometric catalogs and enhance the calibration engine. Removing this barrier to the use of legacy or badly archived data will greatly extend astronomical timelines into the past. This research will facilitate any work with distributed heterogeneous datasets, and create robust and efficient algorithms for solving the fundamental registration problem across many fields of science. The automation of astrometry will free a great deal of future time and effort throughout the community, and the processing of both new and existing material will significantly enhance the available data archives and their use for both science and education.

AST-0428465 Hogg这个项目是计算机科学家和天体物理学家之间的一个国际合作，旨在构建和操作一个天体测量引擎，为过去和未来拍摄的每一幅有用的天文图像创建正确的、基于标准的天体测量标题，无论其处于任何归档混乱状态。 该服务产品将在地面观测站进行开发、测试和安装，提供基于标准的图像坐标和天空坐标之间通常非线性转换的描述，目的是没有“误报”，但可能偶尔会出现“无答案”。 随着产品的成熟，它将从图像中识别的标准返回校准和带通信息，未来的版本甚至可以在没有任何关于近似尺度、位置和方向的先验信息的情况下工作。 一些可信的数据子集将用于改进天体测量星表和增强校准引擎。 消除使用遗留数据或存档不良数据的障碍将大大延长天文时间表。 这项研究将促进任何分布式异构数据集的工作，并创建强大而有效的算法来解决许多科学领域的基本配准问题。 天体测量的自动化将为整个社区节省大量未来的时间和精力，新材料和现有材料的处理将显着增强可用的数据档案及其在科学和教育方面的用途。
