SBs for Dynamic Time and Doppler Tracking

Currently Doppler tracking and Doppler setting is not supported in Array Operations. We thus have disabled Doppler tuning in the OPT. Use sky frequencies and cancel/resubmit new SBs with updated sky frequencies if the change of frequency due to the movement of the earth requires this. Note that for some experiments, this may be on time scales as short as a week (or even worse) to ensure that the frequency/velocity span of our line is located fully in your observed bandwidth. Ask the staff (through the helpdesk) if you need help. You can calculate your sky frequencies using the Online Dopset Tool at http://www.vla.nrao.edu/astro/guides/dopset/ .

We are currently working on a solution to avoid having to redefine the frequency setup every now and then. Please check again every few weeks as this section is the place where we will keep you informed about this.

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.
