摘要:

美国虚拟天文台是一个软件基础设施和开发项目,旨在开始建立一个可操作的虚拟天文台(VO),并为美国提供与国际VO工作的协调。VO的概念是提供一种方法,使天文学家能够无缝地发现,访问和处理数据,而不管其物理位置如何。本文介绍了VAO的起源,包括美国国家虚拟天文台的前身工作,并总结了其主要成就。这些成就包括两个脚本工具包的开发,使科学家将VO数据直接纳入他们的减少和分析环境和高层次的科学应用程序的数据发现,集成,分析和目录交叉比较。通过与国际社会合作,并根据软件开发的经验,虚拟天文台是国际虚拟天文台联盟内国际标准的主要贡献者。虚拟天文台还演示了如何部署一个运行中的虚拟天文台,提供一个强大的运行环境,定期检查世界各地的虚拟天文台服务的有效性和是否符合国际标准。最后,VAO参与了社区外展,开发了一个综合网站,提供在线教程、公告、美国和国际开发的工具和服务的链接,以及展览和实践培训。VAO项目的所有数字产品,包括软件、文档和教程,都存储在一个存储库中,供社区访问。VAO的持久遗产是人们越来越期望新的望远镜和设施在设计其数据管理系统时纳入VO功能。

英文摘要:

The U.S. Virtual Astronomical Observatory was a software infrastructure and development project designed both to begin the establishment of an operational Virtual Observatory (VO) and to provide the U.S. coordination with the international VO effort. The concept of the VO is to provide the means by which an astronomer is able to discover, access, and process data seamlessly, regardless of its physical location. This paper describes the origins of the VAO, including the predecessor efforts within the U.S. National Virtual Observatory, and summarizes its main accomplishments. These accomplishments include the development of both scripting toolkits that allow scientists to incorporate VO data directly into their reduction and analysis environments and high-level science applications for data discovery, integration, analysis, and catalog cross-comparison. Working with the international community, and based on the experience from the software development, the VAO was a major contributor to international standards within the International Virtual Observatory Alliance. The VAO also demonstrated how an operational virtual observatory could be deployed, providing a robust operational environment in which VO services worldwide were routinely checked for aliveness and compliance with international standards. Finally, the VAO engaged in community outreach, developing a comprehensive web site with on-line tutorials, announcements, links to both U.S. and internationally developed tools and services, and exhibits and hands-on training .... All digital products of the VAO Project, including software, documentation, and tutorials, are stored in a repository for community access. The enduring legacy of the VAO is an increasing expectation that new telescopes and facilities incorporate VO capabilities during the design of their data management systems.
