Search Results

Remember that a search automatically selects and switches to the Search Results catalog at the bottom of the search tool. The results of a search are displayed read-only in the familiar SCT table format in a Search Results tree structure with the possibility to sort on different columns (Figure 3.3). Except for the Advanced Search, previous searches are saved in this tree for convenience - navigating to a previous search is done by simply selecting that search. Note that a search will always change from the selected catalog to selecting the search results. Before performing another search in the same catalog, re-select the catalog! Sources presented in the search results - or the whole Search Results catalog - can be selected, and added to a personal source catalog using copy/paste, etc. To delete the results of a search, select the "Search Results" catalog in the search results tree and use EDIT - REMOVE SEARCH RESULTS form the menu strip.

Search results when using the Advanced Search are displayed in a table at the bottom of the page and added in the Search Results tree if it is sufficiently new (i.e., not started from the Search Results page). Following searches, when not leaving the Advanced Search tool, will overwrite the current table with the new search results. Search results are cleared when you log out from the OPT web application.

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.
