Introduction

This appendix does not directly relate to the OPT but does expect you are familiar with it and with its jargon.

Starting with the WIDAR observations in the spring of 2010, the majority of observing with the EVLA will be done by dynamically allocating observing time to the most appropriate SB in the observing queue. Here "most appropriate" typically depends on scientific priority, weather conditions and state of the array. This appendix describes some considerations and choices that might increase your chances to get more of your SBs observed successfully. This assumes that your scientific objectives can be met with a flexible approach while competing with other projects for the LST range to be observed.

Important note: for line observations currently (as of March 2010) there are restrictions on Doppler tracking. See section A.3.

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.
