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.
