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的开创性近红外（NIR）调查设施的出现，英国的观察天文学处于强大的位置，以及ESO成员资格提供的详细跟进机会。天文学的重大进展一直在很大程度上依赖于从无线电到X射线波长的天空调查，而深度NIR调查的新时代是此过程的最新阶段。这也是英国在剑桥和爱丁堡调查部门中拥有大量领先优势和必要的专业知识，以利用这一进展在广阔的天文学中。认识到这一点的好处，ESO现在还通过VST和VISTA望远镜进行了大力致力于公共调查，并更广泛地利用了经过专业处理和归档的科学数据产品。剑桥天文学调查部（CASU）的成员在调查天文学中发挥了领导作用，不仅是通过开拓技术来最佳从调查数据中提取知识，而且还通过在利用此信息来实现世界领先的研究中发挥主动作用。数据处理和剥削之间的这种协同和反馈至关重要。这是一种故意的策略，提供了团体的主要优势和动力。在现代时代，宽阔的数字调查摄像机产生了大量数据，这些数据超出了非专业天文学家的资源能力和分析技能。观察数据的系统管道处理，校准和遗产策划是端到端综合观察策略的基本要求，也是全球虚拟观测站的关键组成部分。已经开发了CASU设施，以通过访问多层数据存储系统和专家管道处理系统来为这一数据雪崩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，而且还将通过开发基础设施来分析这些设施的数据，在极大的望远镜和广播平方公里阵列的时代中也有意义。这项滚动赠款提案建立在已经取得的巨大进步的基础上，并要求为2008 - 2013年期间为CASU提供以下活动的资金：继续操作和维护WFCAM数据处理和校准管道；英国Vista管道的先进开发，增强和运行； VDFS ESO管道可交付成果的维护和升级；在南半球由英国领导的VST公共调查以及北半球的同等前体调查的运营支持和管道处理；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计划的贡献；继续支持维护和开发英国地面望远镜档案；以及该小组研究活性成员的适度研究组成部分。
