Catalog Tables in the RCT and the SCT

Click NRAO defaults in the left-hand side column to return to the NRAO defaults catalog. The table at the top of the main RCT editing or manipulation window (Figure 2.2) has a header line with obvious meanings. (If not, we should have supplied a fly-over help tool-tip for it; the tool-tip help shows up when the mouse hovers over the item for a second or so.) When you move the mouse over the headers you will see that they switch color to orange. Every table column with a header showing this behavior can be sorted by clicking the header. This is so for all other tools as well. A table with more than 25 entries may span multiple pages, but this catalog currently is too short to demonstrate this (see section 3.1.1). When a column is sorted, it will show a small orange arrow next to the header name, pointing up if the column is sorted in ascending order (going to larger values when going down in the table), and pointing down when the sorting is in descending order. A sorted table can be re-sorted in the opposite direction by clicking the column again (note that the header of a sorted column, the one with the arrow, might not change to the orange color anymore).

Each line in the table represents one resource with a name and some descriptive information. A line starts with a tick-box and an edit icon (\includegraphics[height=3mm]{psimg/source.png.ps}). The tick-boxes can be used to select one or more entries in the catalog for copy/paste as described in the next section. A shortcut to select all, or to deselect all catalog entries on the current page can be found above the table. Selecting and copy/paste has to be redone for every page. The \includegraphics[height=3mm]{psimg/source.png.ps} edit icon is used to access the details of the resource entry in the catalog, i.e., the specifics of the hardware and instrument configuration.

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.
