cds-question@unistra.frradio-sourcessurveysastrometryWe present the third extension to the Very Long Baseline Array (VLBA) Calibrator Survey, containing 360 new sources not previously observed with Very Long Baseline Interferometry (VLBI). The survey, based on three 24 hour VLBA observing sessions, fills the areas on the sky above declination -45{deg} where the calibrator density is less than one source within a 4{deg} radius disk at any given direction. The positions were derived from astrometric analysis of the group delays determined at 2.3 and 8.6GHz frequency bands using the CALC/SOLVE software package. The VCS3 catalog of source positions, plots of correlated flux density versus length of projected baseline, and contour plots and FITS files of naturally weighted CLEAN images, as well as calibrated visibility function files, are available electronically from the Goddard Geodetic VLBI Group.2005AJ....129.1163Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/129/1163CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVIII/60 : Interferometer phase calibration sources (Patnaik+ 1998)J/ApJS/141/13 : VLBA calibrator Survey - VCS1 catalog (Beasley+, 2002)J/AJ/126/2562 : Second VLBA calibrator survey: VCS2 (Fomalont+, 2003)http://gemini.gsfc.nasa.gov/vcs3/ : VLBA Calibrator Survey 3 (VCS3)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/129/1163https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/129/1163http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/129/1163https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/129/1163https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/129/1163http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/129/1163GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/129/1163/table2 (The VCS3 catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/129/1163/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/129/1163/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/129/1163/table2?GETtext/xml+votable180.050000true1.02047915417-11.816218233330.0055555555555555566/250 716 742 792 831 1642 1981 1999 2198 2419 2429 2439 2521 3533 3752 4089 4171 4302 4477 4538 4601 4608 4644 5009 5676 5806 5956 6153 6368 7018 7289 7341 7954 8415 8417 8452 8604 8675 8894 8968 9412 9546 9788 9860 10283 10386 10401 10519 10548 10643 11522 11523 11910 11965 12352 12604 12778 12787 13060 13067 13107 13528 13572 13860 13934 13985 14104 14282 14553 14581 14758 14939 14985 15045 15107 15373 15463 15477 15670 15692 15737 16207 16532 16758 16873 17138 17206 17265 17333 17840 17917 18053 18066 18141 18164 18253 18298 18361 18806 19104 19203 19287 19327 19373 19500 19743 19775 19784 19952 20325 20406 20440 20577 20678 20764 20783 20823 20834 20968 20974 20984 21071 21321 21329 21497 21547 21554 21574 21657 21668 21979 22033 22047 22071 22116 22157 22199 22224 22271 22275 22711 22730 22963 23324 23513 23625 23720 23897 24039 24206 24316 24502 24658 24661 24914 25920 26056 26239 26274 26308 26375 26417 26422 26434 26446 26572 26794 26870 27012 27082 27101 27179 27380 27509 27762 27812 28112 28151 28338 28769 28778 28818 28888 28920 28928 28937 28947 28999 29039 29143 29168 29263 29283 29300 29355 29357 29421 29431 29455 29515 29611 29659 29876 29981 30131 30220 30228 30255 30279 30323 30366 30385 30629 30667 30884 30906 30928 31079 31211 31222 31277 31460 31527 31718 31770 31783 31792 31828 31915 31976 32125 32160 32660 34281 34710 35061 35294 35311 35535 35623 35730 35833 35901 36005 36064 36363 36549 36718 36735 36815 38141 38303 38352 38373 38638 38682 38715 38744 38787 38817 38842 38880 38888 39286 39326 39342 39407 39622 39718 39733 39773 39774 39783 39888 39897 39920 39923 40077 40096 40217 40253 40300 40316 40379 40392 40411 40474 40762 40824 40891 40915 40931 42481 42768 42805 42973 43007 43451 43483 43578 43595 43628 43694 43723 43739 43765 43786 43821 43865 43888 44069 44075 44113 44122 44131 44166 44170 44335 44350 44377 44443 44484 44563 46717 46739 46782 46798 46810 46835 46932 46948 47470 47605 47796 47805 47826 47922 48047 48063 48091 48182 48187 48292 48345 48460 48476 48507 48514 48546 48666 48685 48693 48724 48768 48893 48952 49029 490491.5239959695752804e-24 5.5658981862942334e-24https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/129/1163?format=asciiRadiodefaultJ/AJ/129/1163/table2The VCS3 catalogrecnoRecord number assigned by the VizieR team.
