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）测量设施的出现以及ESO成员提供的详细后续行动的机会，英国的观测天文学处于有利地位。天文学的重大进展一直严重依赖于从无线电到X射线波长的天空调查，而深近红外调查的新时代是这一进展的最新阶段。这也是英国在剑桥和爱丁堡调查单位中既有实质性的领先优势又有必要的专业知识来利用广域天文学的这一进步的地方。认识到这一点的好处，ESO现在也致力于通过VST和VISTA望远镜进行公众调查，并更广泛地利用经过专业处理和存档的科学数据产品。在现代，宽视场数字测量相机产生的大量数据远远超出了非专业天文学家的资源能力和分析技能。观测数据的系统管道处理、校准和遗留管理是端到端综合观测战略的基本要求，也是全球虚拟观测站的关键组成部分。Vista数据流系统（VDFS）的开发是为了通过访问多TB数据存储系统、专家管道处理系统和科学用户支持，为这种雪崩式的数据提供最佳的人体工程学解决方案。VDFS处理和分析管道的持续发展不仅将使英国天文学界受益，而且还将通过进一步发展基础设施来分析来自这些设施的数据，从而在超大望远镜和无线电平方公里阵列时代发挥重要作用。这项标准赠款提案是对资源的投标，以完成VDFS的全面开发，从而为英国领导的VISTA公众调查提供全面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。通过在CASU已经取得的巨大进步的基础上，这将使一个具有成本效益的和最佳的解决方案，将大量的VISTA数据转换为完全校准的科学准备的产品成熟的开发问题。
