The positions have been derived from astrometric analysis of dual-frequency 2.3 and 8.4 GHz VLBA snapshot observations; in a majority of cases, images of the sources are also available. These radio sources are suitable for use in geodetic and astrometric experiments, and as phase-reference calibrators in high-sensitivity astronomical imaging. The VCS1 is the largest high-resolution radio survey ever undertaken and triples the number of sources available to the radio astronomy community for VLBI applications. In addition to the astrometric role, this survey can be used in active galactic nuclei, Galactic, gravitational lens, and cosmological studies. 2002ApJS..141...13B https://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/141/13 Catalog Research IsServedBy TAP VizieR generic service IsServedBy Conesearch service related-to VIII/60 : Interferometer phase calibration sources (Patnaik+ 1998) https://cds.unistra.fr/vizier-org/licences_vizier.html https://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/141/13 https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/141/13 http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/141/13 https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/141/13 https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/141/13 http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/141/13 GET text/xml+votable https://tapvizier.cds.unistra.fr/TAPVizieR/tap Cone search capability for table J/ApJS/141/13/table2 (VCS1 Catalog) https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/141/13/table2? https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/141/13/table2? http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/141/13/table2?
