cds-question@unistra.frradio-sourcessurveysastrometryThis paper presents an extension of the Very Long Baseline Array Calibrator Survey, called VCS2, containing 276 sources. This survey fills in regions of the sky that were not completely covered by the previous VCS1 calibrator survey. The VCS2 survey includes calibrator sources near the Galactic plane, -30{deg}<DE<-45{deg}, and VLA calibrators. The positions have been derived from astrometric analysis of the group delays measured at 2.3 and 8.4 GHz using the Goddard Space Flight Center CALC/SOLVE package. From the VLBA snapshot observations, images of the calibrators are available, and each source is given a quality code for anticipated use. The VCS2 catalog is available from the NRAO Web site.2003AJ....126.2562Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/126/2562CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVIII/60 : Interferometer phase calibration sources (Patnaik+ 1998)J/ApJS/141/13 : VLBA calibrator Survey - VCS1 catalog (Beasley+, 2002)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/126/2562https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/126/2562http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/126/2562https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/126/2562https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/126/2562http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/126/2562GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/126/2562/table3 (The VCS2 Source List)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/126/2562/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/126/2562/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/126/2562/table3?GETtext/xml+votable180.050000true0.0849997917-32.35034286110.0055555555555555566/1025 1129 1309 1342 1413 1423 1433 1435 1460 1787 2927 3024 3050 3052 3158 3161 3183 3272 3330 3541 3644 3654 3656 3659 3712 3882 3918 4285 5271 5432 5598 6532 7709 8216 8220 9003 10288 10474 10654 10986 11502 11714 11806 11876 11927 12276 12370 12571 12879 13224 13582 14282 14291 14343 14357 14400 14413 14428 14539 14603 14618 14637 14641 15377 15429 15641 15659 15683 16253 16411 16444 16483 16485 16489 16509 16518 17514 18323 19060 19321 19487 19546 19653 19750 19883 19886 19946 20101 20500 20507 20610 20819 21071 21129 21136 21632 21704 22066 23436 23850 23946 24150 24165 24326 24346 24353 24615 24635 24658 24672 24724 24784 28673 28818 28824 28897 29110 29522 29558 29620 30021 30315 30416 30431 30507 30511 30542 30683 30705 30836 31986 31998 32068 34168 34227 34233 34281 34296 34487 34489 34534 34551 34591 34606 34614 34665 34691 34710 35192 35249 35256 35274 35281 35309 35318 35432 35482 35487 35491 35501 35523 35549 35562 35577 35579 35581 35590 35623 35648 35651 35680 35720 35722 35786 35849 35897 35918 36003 36028 38358 38383 38397 38470 38474 38502 38583 38591 38639 38646 38800 38802 39287 39326 39342 39347 39354 39392 39398 39407 39542 39557 39566 39577 39592 39654 39664 39672 39718 39728 39740 39747 39752 39828 39940 39946 39970 39974 39982 39987 39997 40024 40036 40083 40333 40353 40479 40527 40633 40635 42366 42609 42853 42883 43257 43399 43469 43628 43723 43739 43835 43837 43841 43876 43914 43918 44035 44047 44088 46388 46394 46398 46444 46459 46546 46568 46577 46709 46762 46851 46931 46939 47419 47585 47672 47826 47943 48142 48362 485291.5239959695752804e-24 1.5239959695752804e-24https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/126/2562?format=asciiRadiodefaultJ/AJ/126/2562/table3The VCS2 Source ListrecnoRecord number assigned by the VizieR team.
