Observational astronomy in the UK is in a strong position with the advent of the pioneering near-infrared (NIR) survey facilities of VISTA and WFCAM and the opportunities for detailed followup provided by membership of ESO. Significant advances in astronomy have always relied heavily on surveys of the sky from radio, through optical to X-ray wavelengths and the new era of deep NIR surveys is the latest stage in this progression. It is also one where the UK has both a substantial lead and the requisite expertise in the Cambridge and Edinburgh survey units to exploit this advance in wide field astronomy. Recognising the benefits of this, ESO are now also heavily committed to public surveys through the VST and VISTA telescopes and to wider exploitation of expertly processed and archived science data products. Members of the Cambridge Astronomy Survey Unit (CASU) have played a leading role in survey astronomy, not only by pioneering techniques to optimally extract knowledge from survey data, but also by taking a proactive role in exploiting this information to produce world-leading research. This synergy and feedback between data processing and exploitation is crucial. It has been a deliberate strategy that has provided the main strength and motivation of the group. In the modern era wide-field digital survey cameras produce enormous volumes of data that are way beyond the resource capacity and analysis skills of non-specialist astronomers. Systematic pipeline processing, calibration and legacy curation of observational data are a fundamental requirement of an end-to-end integrated observing strategy and a crucial component of a global Virtual Observatory. The CASU facility has been developed to allow an optimal ergonomic solution to this avalanche of data, through access to multi-Tbyte data storage systems and expert pipeline processing systems. Continuing development of the CASU processing and analysis pipelines will not only benefit the UK astronomy community now, but will also be relevant in the era of Extremely Large Telescopes and the radio Square Kilometer Array, by developing the infrastructure to analyse the data from these facilities. This rolling grant proposal builds on the tremendous advances already made and requests funding for CASU for the period 2008-2013 for the following activities: continued operation and maintenance of the WFCAM data processing and calibration pipeline; advanced development, enhancement, and operation of the UK VISTA pipelines; maintenance and upgrades for the VDFS ESO pipeline deliverables; operational support and pipeline processing for the UK-led VST public surveys in the southern hemisphere and the equivalent precursor surveys in the northern hemisphere; support to provide a range of science data products and services as a UK contribution to the global Virtual Observatory initiative; continuation of support for maintaining and developing the UK ground-based telescope archives; and a modest research component for the research-active members of the group.

随着 VISTA 和 WFCAM 等开创性近红外 (NIR) 巡天设施的出现，以及 ESO 成员提供的详细跟进机会，英国的观测天文学处于强势地位。天文学的重大进步一直在很大程度上依赖于从无线电、光学到 X 射线波长对天空的调查，而深度近红外调查的新时代是这一进展的最新阶段。英国在剑桥和爱丁堡勘测单位中也拥有显着的领先地位和必要的专业知识，以利用广域天文学的这一进步。认识到这样做的好处，ESO 现在也大力致力于通过 VST 和 VISTA 望远镜进行公共调查，并更广泛地利用经过专业处理和存档的科学数据产品。剑桥天文学调查组 (CASU) 的成员在调查天文学中发挥了主导作用，不仅通过开创性技术从调查数据中最佳地提取知识，而且还积极利用这些信息来开展世界领先的研究。数据处理和利用之间的协同和反馈至关重要。这是一项深思熟虑的战略，为集团提供了主要力量和动力。在现代，宽视场数字巡天相机产生的大量数据远远超出了非专业天文学家的资源容量和分析技能。观测数据的系统化管道处理、校准和遗留管理是端到端综合观测策略的基本要求，也是全球虚拟天文台的重要组成部分。 CASU 设施的开发旨在通过访问多 TB 数据存储系统和专家管道处理系统，为大量数据提供最佳的人体工程学解决方案。 CASU 处理和分析管道的持续开发不仅将使英国天文学界受益，而且通过开发分析这些设施数据的基础设施，也将在超大望远镜和射电平方公里阵列时代发挥重要作用。这项滚动赠款提案建立在已经取得的巨大进展的基础上，并要求为 CASU 在 2008 年至 2013 年期间提供资金，用于以下活动： WFCAM 数据处理和校准管道的持续运行和维护；英国 VISTA 管道的先进开发、增强和运营； VDFS ESO 管道可交付成果的维护和升级；为英国主导的南半球 VST 公共调查和北半球同等前体调查提供业务支持和管道处理；支持提供一系列科学数据产品和服务，作为英国对全球虚拟天文台倡议的贡献；继续支持维护和发展英国地面望远镜档案；以及为小组中积极研究的成员提供适度的研究部分。
