Cass A seen by radio.
Here is a sky viewer with the amateur radio astronomer in mind. RSP 1.2 is not just a sky viewer with a radio source database. It was originally written as an observation scheduling tool. From there it evolved into useful educational device. We are not trying to fool you. This is a program written for the DOS operating system. As such, it is not as graphically advanced as a lot of modern Windows programs.... but just look at what it can do:
The sky can be displayed in galactic or equatorial coordinates. There is even a polar view available for the sky within 30 degrees of the celestial poles. Pulsars, supernova remnants, extragalactic sources such as active galaxies and quasars, the Sun, and Jupiter, are all available to you. What's more, the database is completely open ended. We even provide you with the tools to make your own database for RSP 1.2. Information screens (like the one above) and spectral tabulations are available for sources at the press of a mouse button. You can establish an observing schedule with source transit information with just two button presses! A schedule file is produced which can be used to automate your radio telescope observations. Throw your radio telescope beam pattern on the screen and maintain a real time display of what sources are in your antenna pattern. Other features include:
The RSP Formatted Multiple Survey Catalog 1.0 This is a compilation of 6734 radio source records of flux greater than or equal to 10 Janskys. The information was extracted from from a "master source list". The nature of this catalog differs from others published by Radio-Sky in that no effort was was made to combine multiple observations of a single source into one record. Thus, fewer than six thousand different sources are actually represented. The multiple observations still have importance in that most were done at different frequencies.

Parkes Survey in RSP Format - This diskette contains a catalog of 5051 sources extracted from the PKSCAT90 catalog. The sources herein are those which exhibit a flux density of at least 1 Jansky at one of the observed frequencies. The original survey and catalog are the results of work done by the Australian Telescope National Facility. Sources in the galactic plane and within the Large Magellanic Cloud are largely excluded, as these sources were the subjects of other detailed surveys. Telescopes used for the survey included the Parkes radio telescope and telescopes at the Molonglo and Culgoora observatories.
The RSP Formatted Green Bank 4.85 Ghz Sky Survey This is a compilation of 10,549 sources of flux greater than or equal to 100 millijanskys (.1 Janskys), at 4.85 Ghz, extracted from the 87GB catalog of radio sources. The survey covers 0 to 75 degrees in declination. Sources of more than 20 arcminutes in extent are suppressed. Some strong sources are thus not represented. The survey was taken using the now defunct 300 ft. telescope at the National Radio Astronomical Observatory in Green Bank, West Virginia.
