TL;DR
The Keck Observatory Archive (KOA) manages and provides access to observational data from Keck telescopes, having ingested all data from eight instruments by 2013 and continuing to expand with new data at 4 TB annually.
Contribution
This paper details the design, operation, and data management policies of KOA, including its comprehensive data ingestion and public access strategies.
Findings
All eight active instrument data ingested by 2013
Archive continues to ingest new data at 4 TB per year
Approximately two-thirds of data are publicly accessible
Abstract
The Infrared Processing and Analysis Center (IPAC) and the W. M. Keck Observatory (WMKO) operate an archive for the Keck Observatory. At the end of 2013, KOA completed the ingestion of data from all eight active observatory instruments. KOA will continue to ingest all newly obtained observations, at an anticipated volume of 4 TB per year. The data are transmitted electronically from WMKO to IPAC for storage and curation. Access to data is governed by a data use policy, and approximately two-thirds of the data in the archive are public.
