Precise astrometry with VLBA (VIPS) J/AJ/142/89 ivo://CDS.VizieR/J/AJ/142/89 doi:10.26093/cds/vizier.51420089 CDS Petrov L. Taylor G.B. 2018-01-04T08:22:55Z 2012-03-01T16:41:17Z CDS support team CDS, Observatoire de Strasbourg, 11 rue de l'Universite, F-67000 Strasbourg, France cds-question@unistra.fr astrometry very-long-baseline-interferometry optical-observation catalogs radio-sources We present accurate positions for 857 sources derived from the astrometric analysis of 16 eleven-hour experiments from the Very Long Baseline Array imaging and polarimetry survey at 5GHz (VIPS). Among the observed sources, positions of 430 objects were not previously determined at milliarcsecond-level accuracy. For 95% of the sources the uncertainty of their positions ranges from 0.3 to 0.9mas, with a median value of 0.5mas. This estimate of accuracy is substantiated by the comparison of positions of 386 sources that were previously observed in astrometric programs simultaneously at 2.3/8.6GHz. Surprisingly, the ionosphere contribution to group delay was adequately modeled with the use of the total electron content maps derived from GPS observations and only marginally affected estimates of source coordinates. 2011AJ....142...89P https://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/142/89 Catalog Research IsServedBy TAP VizieR generic service IsServedBy Conesearch service related-to J/ApJ/658/203 : VLBA imaging and polarimetry survey at 5GHz (Helmboldt+, 2007) J/ApJ/671/1355 : EGRET blazars in VIPS (Taylor+, 2007) J/AJ/143/35 : KCAL VERA 22 GHz calibrator survey (Petrov+, 2012) https://cds.unistra.fr/vizier-org/licences_vizier.html https://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/142/89 https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/142/89 http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/142/89 https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/142/89 https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/142/89 http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/142/89 GET text/xml+votable https://tapvizier.cds.unistra.fr/TAPVizieR/tap Cone search capability for table J/AJ/142/89/table2 (VIPS (Very Long Baseline Array imaging and Polarimetry Survey) catalog of 857 sources) https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/142/89/table2? https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/142/89/table2? http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/142/89/table2?
