The Astrophysics Research Knowledgebase (ARK) is a
service provided by NASA's High Energy Astrophysics Science Archive
Research Center (HEASARC) designed to create a user database of results
related to the archival data hosted by the HEASARC. ARK provides a web
interface to submit and search information stored in the database.
ARK is also used for the HEASARC's Remote Proposal System
(RPS), supporting a variety of missions.
Registration is required to access this service. Users are given permissions
to submit to and/or search specific tables in the database based on their needs.
If a group of users wants to collaborate and share results via ARK,
contact our help desk.
