European VLBI Network Data Archive

The European VLBI Network (EVN) is an interferometric array of radio telescopes located primarily in Europe and Asia, with additional telescopes in South Africa and Puerto Rico. The EVN performs high-resolution observations of cosmic radio sources at wavelenghts from 92cm to 7mm. The EVN Data Archive contains, among other things, the correlated data from EVN observations plus pipeline output, including the initial calibration tables to apply to the correlated data and preliminary images. In general, the correlated data and some pipeline results are proprietary for one year following distribution to the PI of the final epoch of observations resulting from a proposal after which the data enters the public domain; more details are in the "EVN Data Access Policy" linked via the archive-introduction page.

欧洲甚长基线网（EVN）主要位于欧洲和亚洲的无线电望远镜阵列，同时在南非和波多黎各也设有辅助望远镜。EVN对宇宙无线电源进行高分辨率观测，观测波长范围从92厘米至7毫米。EVN数据档案包含诸如EVN观测的相关数据以及管道输出等多种内容，包括应用于相关数据的初始校准表和初步图像。通常，自相关数据及部分管道结果自分配给最终观测纪期末期提案负责人（PI）之日起一年内为专有信息；详情请参阅通过档案介绍页面链接的“EVN数据访问政策”。
