cds-question@unistra.frradio-sourcesastrometryvery-long-baseline-interferometryThis catalog contains observations from 600 Mark III VLBI experiments from conducted between 1979 to 1988. These experiments resulted in 237681 acceptable pairs of group delay and phase delay rate observations. These have been used to derive positions of 182 extra-galactic radio sources with typical formal standard errors less than 1 mas. The right ascension zero point of this reference frame has been aligned with the FK5 by using the optical positions of 28 extragalactic radio sources whose positions are on the FK5 system. Also included are the Mark III VLBI stations and a summary of the analysis configuration.1990AJ.....99.1284Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/I/151CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=I/151https://vizier.iucaa.in/viz-bin/VizieR-2?-source=I/151http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=I/151https://vizier.cds.unistra.fr/viz-bin/votable?-source=I/151https://vizier.iucaa.in/viz-bin/votable?-source=I/151http://vizieridia.saao.ac.za/viz-bin/votable?-source=I/151GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table I/151/table3 (Source positions (J2000) from GLB353 solution)https://vizier.cds.unistra.fr/viz-bin/conesearch/I/151/table3?https://vizier.iucaa.in/viz-bin/conesearch/I/151/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/I/151/table3?GETtext/xml+votable180.050000true1.5578885625-6.3931480750.005555555555555556Cone search capability for table I/151/table4 (FK5 optical positions of 28 extragalactic)https://vizier.cds.unistra.fr/viz-bin/conesearch/I/151/table4?https://vizier.iucaa.in/viz-bin/conesearch/I/151/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/I/151/table4?GETtext/xml+votable180.050000true20.4869413894.3735402780.005555555555555556https://cdsarc.cds.unistra.fr/viz-bin/moc/I/151?format=asciiRadiodefaultI/151/table3Source positions (J2000) from GLB353 solutionrecnoRecord number assigned by the VizieR team.
