摘要

W.M.凯克天文台档案馆（KOA）发布了观测者数据访问门户（ODAP），这是一个网络应用程序，可将W.M.凯克天文台的天文数据近乎实时地传送给计划项目的主要研究人员及其在世界任何地方的合作者。数据文件及其相关元数据在写入磁盘并存档到 KOA 后，会立即流式传输到用户的台式机上。ODAP 用户界面由 React 构建，使用 WebSocket 协议在 KOA 和用户之间传输数据。本文档介绍了该工具的设计、遇到的挑战，展示了如何将 ODAP 集成到 Keck 观测模型中，并提供了使用指标分析。

Observers' Data Access Portal: Realtime Streaming for Astronomical Data

The W. M. Keck Observatory Archive (KOA) has released the Observers Data Access Portal (ODAP), a web-application that delivers astronomical data from the W. M. Keck Observatory to the scheduled program's principal investigator and their collaborators anywhere in the world in near real-time. Data files and their associated metadata are streamed to a user's desktop machine moments after they are written to disk and archived in KOA. The ODAP User Interface is built in React and uses the WebSocket protocol to stream data between KOA and the user. This document describes the design of the tool, challenges encountered, shows how ODAP is integrated into the Keck observing model, and provides an analysis of usage metrics.
