Web access

The archive system implements a very simple search interface that permits queries by coordinates and radius as well as by other parameters of interest. The user can also select the maximum number of sources to return (with values from 10 to unlimited).

The result of the query is a HTML table with all the sources found in the archive fulfilling the search conditions. Information on the output fields can be obtained placing the mouse over the question mark (?) close to the name of the column. The archive implements the SAMP (Simple Application Messaging) protocol. SAMP allows Virtual Observatory applications to communicate with each other in a seamless and transparent way for the user. This way, the results of a query can be easily transferred to other VO applications by just clicking the "Send table to VO Apps" button.
