Web access

The archive system implements a very simple search interface that permits queries by coordinates/radius and or range (*) of magnitudes. The default search radius is set to 5 arcsec. The user can also select the maximum number of sources to return (with values ranging from 10 to unlimited).

The result of the query is a HTML table with all the sources found in the archive fulfilling the search criteria. Detailed information on the output fields can be obtained placing the mouse over the question mark ("?") located close to the name of the column. Results can be sorted by just clicking on 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.

(*) When a range is specified in a search the user must give both a minimum and maximum value for the corresponding quantity. If only a minimum value is given, all results with values larger than that will be obtained. If only a maximum value is given, all results with values smaller than that will be obtained.

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.
