我们描述了Vista科学档案馆(VSA)及其首次公开发布的数据，这些数据来自Vista的六项公共调查中的五项。VSA的存在是为了支持Vista调查的整个生命周期：Vista公共调查联合体可以在将调查数据产品提交给ESO科学档案设施(ESO SAF)之前进行质量控制评估时使用它；它支持他们在调查数据发布之前通过ESO SAF利用调查数据；随后，它向更广泛的社区提供调查科学利用工具，以补充ESO SAF的数据产品储存库功能。这份白皮书是在通过VSA首次公开发布公共调查数据的同时撰写的，旨在帮助其用户了解可用的数据产品以及VSA的功能如何支持他们的各种科学目标。我们描述了数据库的设计，并概述了数据库驱动的整理过程，这些过程从每晚管道处理和校准的FITS文件中获取数据，以创建科学就绪的调查数据集。这种设计的大部分以及实现它的代码库都来自我们早期的WFCAM科学档案(WSA)，因此本文集中在Vista特定的方面，并根据运行WSA的经验对系统进行了改进。
We describe the VISTA Science Archive (VSA) and itsfirst public release of data from five of the six VISTA public surveys. The VSA exists to support the VISTA surveys through their lifecycle: the VISTA Public Survey consortia can use it during their quality control assessment of survey data products before submission to the ESO Science Archive Facility (ESO SAF); it supports their exploitation of survey data prior to its publication through the ESO SAF; and, subsequently, it provides the wider community with survey science exploitation tools that complement the data product repository functionality of the ESO SAF. This paper has been written in conjunction with the first public release of public survey data through the VSA and is designed to help its users understand the data products available and how the functionality of the VSA supports their varied science goals. We describe the design of the database and outline the database-driven curation processes that take data from nightly pipeline-processed and calibrated FITS files to create science-ready survey datasets. Much of this design, and the codebase implementing it, derives from our earlier WFCAM Science Archive (WSA), so this paper concentrates on the VISTA-specific aspects and on improvements made to the system in the light of experience gained in operating the WSA.
