The LIGO Open Science Center

我们建议开始开发LIGO开放科学中心(LOSC)，这将使更广泛的用户社区能够访问LIGO数据。LOSC将收集由LIGO实验室和LIGO科学协作(LSC)及其伙伴科学协作产生的相关数据产品，并向外部用户提供这些数据产品以及为这些用户的目标提供的工具和支持。LOSC将在高级LIGO观测运行之前、运行期间和运行之后运行，提供没有资金支持或以任何其他方式可用的用户服务。数据产品由LIGO实验室和LSC提供，将包括低延迟暂态GW事件候选广播；关于确认的瞬变和长持续检测的信息的目录；6个月间隔的完整应变时间序列数据流以及相关的数据质量信息；以及与所有LIGO和LSC出版物相关的数字数据产品。完成后，LIGO将提供(A)门户网站、客户端工具和一层数据访问服务，通过这些服务，用户可以发现和访问LIGO的一系列数据和元数据产品；(B)长期数据管理；(C)用户文件、服务台、在线教程和用户反馈论坛；(D)赞助教程、讲习班和会议，帮助用户从数据中获得最大的科学知识，并相互交流他们的经验和研究结果给LSC；以及(E)LIGO以数据为中心的资源，以促进LIGO和LSC关于引力波和相关科学的教育和公共宣传工作。在2013财年，我们将开始LOSC的初始开发阶段，并为在高级LIGO运营时代(2014财年及以后)继续开发和部署奠定基础。LOSC公开发布LIGO数据将使人们能够广泛参与引力波物理和天体物理的发展。数值相对论者、相对论理论家、天文学家和天体物理学家将使用LIGO观测来更好地了解强弯曲时空的动力学，以及引力波源的起源和性质。LOSC将在相对论和天体物理学领域实现跨学科科学，使科学家能够提出更深层次的问题，并将该领域带入新的方向。它将与NASA和NSF虚拟天文台的其他天文数据系统互操作，以实现联合数据挖掘和与其他档案的交叉引用。它将通过与法国、印度、意大利和日本的引力波项目的互动，促进国际上开放数据的努力。它将通过在遥远的未来提供和使用数据来扩展和利用LIGO观测。它将使LIGO数据能够用于全国和世界各地的大学本科生和研究生以及业余和专业科学家的教育。通过LIGO实验室的活动和LSC的外联工作，它将为公众宣传提供资源，以培养青年科学家和公众对引力波和多信使天文学的兴趣和兴趣。

We propose to begin the development of the LIGO Open Science Center (LOSC), which will give access to LIGO data to a broad user community. The LOSC will gather relevant data products generated by the LIGO Laboratory and the LIGO Scientific Collaboration (LSC) and its partner scientific collaborations, and make those data products available to outside users along with tools and support for those users' goals. The LOSC will operate before, during, and beyond operation of the Advanced LIGO observations, providing user services that are not funded or available in any other way. Data products, supplied by LIGO Laboratory and the LSC, will include low-latency transient GW event candidate broadcasts; catalogs with information about confirmed transient and long-duration detections; the full strain time series data stream in 6 month intervals with associated data quality information; and digital data products associated with all LIGO and LSC publications. When completed, the LOSC will provide (a) a web portal, client tools, and a layer of data access services through which the user can discover and access a range of LIGO data and metadata products; (b) long-term data curation; (c) user documentation, helpdesk, online tutorials, and user feedback forums; (d) sponsorship of tutorials, workshops and conferences to help users derive maximal science from the data and communicate their experiences and findings to each other and to the LSC; and (e) LIGO data-centric resources to facilitate LIGO and LSC education and public outreach efforts about gravitational wave and related science. In FY13 we will begin the initial development phase of the LOSC and provide a foundation for continued development and deployment in the era of Advanced LIGO operations (FY14 and beyond). The public release of LIGO data by the LOSC will enable broad participation in the advancement of gravitational wave physics and astrophysics. Numerical relativists, relativity theorists, and astronomers and astrophysicists will use LIGO observations to better understand the dynamics of strongly curved spacetime, and the origins and properties of gravitational wave sources. The LOSC will enable cross-disciplinary science throughout the relativity and astrophysics community, enabling scientists to ask deeper questions and carry the field in new directions. It will be interoperable with other astronomy data systems from both NASA and the NSF Virtual Observatory, to enable joint data mining and cross-referencing with other archives. It will promote international efforts for open data through interactions with gravitational wave projects in France, India, Italy, and Japan. It will extend and leverage the LIGO observations by making data available and usable into the far future. It will enable the use of LIGO data for education of university undergraduates and graduate students, and amateur and professional scientists, throughout the nation and the world. Through the activities of LIGO Laboratory and LSC outreach efforts, it will provide resources for public outreach to build interest and excitement in gravitational wave and multi-messenger astronomy in young scientists and the public.
