The accuracy in position and flux density of 19 large radio continuum source catalogues has been determined using SPECFIND, a new tool recently made available through the CDS. The ˜ 67 000 radio continuum spectra with three or more frequencies produced by SPECFIND were used to cross-correlate sources from different catalogues and to calculate...

A new tool to extract cross-identifications and radio continuum spectra from radio catalogues contained in the VIZIER database of the CDS is presented. The code can handle radio surveys at different frequencies with different resolutions. It has been applied to 22 survey catalogues at 11 different frequencies containing a total of 3.5 million...

The Institut de mecanique celeste et de calcul des ephemerides (IMCCE, Paris Observatory) is willing to provide information on Solar System objects to the Astronomical Virtual Observatory. The first step is the interconnection of IMCCE ephemerides servers with the Vizier and Aladin tools of the Centre de donnees astronomiques de Strasbourg...
