Purpose and Scope

Associated Universities, Inc. (AUI) conducts its management and operations of its corporate functions and Research Centers, including the National Radio Astronomy Observatory (NRAO) and the Green Bank Observatory (GBO), collectively referred to as “the Observatory.” This document defines the core policies for use of the AUI’s operational research facilities of the Karl G. Jansky Very Large Array (VLA), the Very Long Baseline Array (VLBA), and the Robert C. Byrd Green Bank Telescope (GBT). The policies concerning the Atacama Large Millimeter/submillimeter Array (ALMA) are maintained independently. Users of ALMA should refer to the documents available online at https://almascience.nrao.edu/documents-and-tools.

The long-term policies set forth in this document supersede other documents in circulation. The Call for Proposals contains the implementation parameters and procedures for the call; however, when in conflict with the policies defined in this document, the NRAO Users’ Policies takes precedence unless explicitly stated.
