This JAVA interface gives the possibility for working with the radio emission data of radio sources in clusters of galaxies from the Cluster database.
You can run the JAVA applet for browsing of radio spectral data and for calculation of parameters of their radio spectrum, if the radio source is in a cluster and has one or more flux density measurements included in the Cluster database in radio data format
For this, after loading the document with optical (or radio) data for the requested cluster, click on [radio spectra (1.2 or 1.1)] in the top line of the document and then choose interface version which is compatible with your Internet-browser. At present there are the versions released on Java Development Kits(JDK)1.1 and JDK1.2. For more information about the JDK support in the browsers see Java for browsers . You can directly run the spectral interface by clicking on 1.2 or 1.1 links.
After that you find the new browser window on your display for help information.
Two other windows, the Main Panel and the Graphic Info, give you different possibilities for browsing of radio emission data of radio sources in clusters of galaxies and for calculation of radio spectral parameters.
You can call the Resolution window using the Setup button that will help you to select more comfortable sizes of all interface windows.
You can find more detail information about the interface services in the graphic manipulations , the approximation options, the radio luminosity and the radio power calculation helps .
Good luck in your work!
