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. 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 Vista Data Flow System (VDFS) has been developed to allow an optimal ergonomic solution to this avalanche of data, through access to multi-Tbyte data storage systems, expert pipeline processing systems and science user support. Continuing development of the VDFS 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 further developing the infrastructure to analyse the data from these facilities. This standard grant proposal is a bid for resource to complete the full development of the VDFS and thereby provide fully integrated data processing support for the UK-led VISTA public surveys. This also includes the operational equipment necessary to carry out the data processing and store the data products. By building on the tremendous advances already made at CASU this will enable a cost-effective and optimal solution to the problem of converting the enormous quantities of VISTA data to fully calibrated science-ready products ripe for exploitation.

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。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Vista数据流系统（VDFS），以通过访问多层数据存储系统，专家管道处理系统和科学用户支持，从而允许对这一数据雪崩的最佳人体工程学解决方案。 VDFS处理和分析管道的持续开发不仅将使英国天文学界受益，而且还将通过进一步开发基础架构来分析这些设施的数据，这在极大的望远镜和无线电平方公里阵列的时代也将与众不同。该标准赠款提案是对资源的竞标，可以完成VDF的全面开发，从而为英国领导的Vista公共调查提供完全集成的数据处理支持。这还包括进行数据处理和存储数据产品所需的操作设备。通过基于CASU已经取得的巨大进步，这将使能够为将大量Vista数据转换为完全校准科学准备就绪的产品以使其成熟以进行开发的问题。
