This Users’ Policies document attempts to maintain consistency with the ALMA Users’ Policies Document when applicable; however, it is independent from the ALMA version and should be treated so.

The majority of these policies and guidelines are taken from the existing online documentation available at https://science.nrao.edu, which has been maintained diligently by Observatory staff over the years. As noted earlier, this information and policies in this document supersede the online content and other documents if conflicts exist.

Founded in 1956, the NRAO provides state-of-the-art radio telescope facilities for use by the international scientific community. NRAO telescopes are open to all astronomers regardless of institutional or national affiliation. Observing time on NRAO telescopes is available on a competitive basis to qualified scientists after evaluation of research proposals on the basis of scientific merit, the capability of the instruments to do the work, and the availability of the telescope during the requested time. NRAO also provides both formal and informal programs in education and public outreach for teachers, students, the general public, and the media.
