Technical Justification

This is where you specify how the technical set-up requested for your proposal enables the scientific goals to be met. For each telescope the page is organized as a series of technical cues with associated text boxes. For example, the user is asked to justify the proposed receivers, back end modes, sensitivity required, total time requested, etc. Links are provided that direct the user to documentation on each of the relevant topics. The technical justification should be thorough and clear despite the small text box sizes. Please enter ascii text and do not use LaTex.

Results from sensitivity/exposure calculators are not yet integrated into the PST. For the GBT cut/paste output from the sensitivity calculator directly into the relevant text box. For the VLA use the Browse/Upload buttons to upload exposure calculator graphics in pdf format. For VLBA/HSA proposals, a png file of the EVN exposure calculator should be uploaded. There are different ways of making such a png file as noted in the cue. For solar observations, the VLA exposure calculator is used to specify the configuration and band but the sensitivity derived is irrelevant. Please use other sections of the technical justification to justify the time request and the observing mode(s) employed.

More than one file can be uploaded (e.g. for different resources).

Input is required for all fields. If a field is not relevant for your proposal then enter "NA" into the text box for "not applicable.''

Connect with NRAO

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

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.

The National Science Foundation (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.
