Abstract

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.
