Observers' Data Access Portal at KOA
For all active instruments, the Keck Observatory Archive (KOA) (https://koa.ipac.caltech.edu) now ingests raw data from the Keck Telescopes within 1 minute of acquisition, quick look reduced data within 5 minutes of creation, and science-ready reduced data for four instruments as they are created by their automated pipelines. On August 1 2023, KOA released the Observers’+ Data Access Portal (ODAP), which enables observers at the telescope and their collaborators anywhere in the world to securely monitor and download science, calibration and quicklook data as they are ingested into the archive. The portal is built using Python socketio websockets, which ensure that metadata appear in the portal as the data themselves are ingested. The portal itself is a dynamic web interface built with React. It enables users to view and customize metadata fields, filter metadata according to data type, and download data as they are ingested or in bulk through WGET scripts. Observers have used the ODAP since its release and have provided feedback that will guide future releases.
