Web access
The archive system provides an interface that permits to visualize a HTML table of data. The user can select the maximum number of entries to return (with values ranging from 10 to unlimited).
Detailed information on the output fields can be obtained placing the mouse over the question mark ("?") located close to the name of the column.
The archive implements the SAMP (Simple Application Messaging Protocol). SAMP allows 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.
Virtual Observatory access
The Virtual Observatory (VO) is an international initiative whose primary goal is to provide an efficient access and analysis of the information hosted in astronomical archives and services. Having a VO-compliant archive is an important added value for an astronomical project to guarantee the optimum scientific exploitation of their datasets.
Our archive system has been designed following the IVOA standards and requirements. In particular, it implements the Cone Search protocol, a standard defined for retrieving records from a catalogue of astronomical sources. The query made through the Cone Search service describes a sky position and an angular distance, defining a cone on the sky. The response returns a list of astronomical sources from the catalogue whose positions lie within the cone, formatted as a VOTable.
