Introduction

Assuming you already have successfully logged in to the OPT web application, and assuming that there is no message in the Important Message Banner that makes you decide to abandon the OPT for the moment, look for the navigation bar at the top. If Sources is not in bold face, but in normal font and underlined, navigate to the SCT (Figure 3.1).

A short introduction to the layout of this tool's page has been given in the introduction (Chapter 1), and more details on some of the features to expect were presented in the RCT tour (Chapter 2). It is assumed that the contents of these chapters are familiar. There should be a source search tool at the top in the left hand side column and at least one VLA catalog visible in the catalog browser in the bottom part (Figure 3.1). Like for the RCT, for orientation and to get a feel for the tool(s), it is instructive to walk through this catalog. After this orientation it should be almost intuitive to create your own personal source catalog(s) which you will use in your project's SB scans.

Connect with NRAO

The NSF National Radio Astronomy Observatory and NSF Green Bank Observatory are facilities of the U.S. National Science Foundation operated under cooperative agreement by Associated Universities, Inc.

Founded in 1956, the NSF NRAO provides state-of-the-art radio telescope facilities for use by the international scientific community. NSF NRAO telescopes are open to all astronomers regardless of institutional or national affiliation. Observing time on NSF 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. NSF NRAO also provides both formal and informal programs in education and public outreach for teachers, students, the general public, and the media.

The U.S. National Science Foundation (U.S. NSF) is an independent federal agency created by Congress in 1950 "to promote the progress of science; to advance the national health, prosperity, and welfare; to secure the national defense..."

AUI collaborates with the scientific community and research sponsors to plan, build, and operate cutting-edge facilities. We cultivate excellence, deliver value, enhance education, and engage the public.
