cds-question@unistra.frastrometryradio-galaxiessurveysWe present the results of a survey of radio continuum sources near the Galactic plane using the Very Long Baseline Array (VLBA). Our observations are designed to identify compact extragalactic sources of milliarcsecond size that can be used for parallax measurements in the Bar and Spiral Structure Legacy Survey. We selected point sources from the NVSS and CORNISH catalogs with flux densities above 30mJy and within 1.5{deg} of known maser targets. Of the 1529 sources observed, 199 were detected. For sources detected on three or more baselines, we determined accurate positions and evaluated their quality as potential calibrators. Most of the 1330 sources that were not detected with the VLBA are probably of extragalactic origin.2011ApJS..194...25Ihttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/194/25CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVIII/85 : SPECFIND V2.0 Catalog of radio continuum spectra (Vollmer+ 2009)VIII/65 : 1.4GHz NRAO VLA Sky Survey (NVSS) (Condon+ 1998)J/MNRAS/390/819 : Combined NVSS-FIRST Galaxies (CoNFIG) sample (Gendre+, 2008)J/MNRAS/357/1231 : Texas-Oxford NVSS (TONS) radio galaxies (Brand+, 2005)http://www.mpifr-bonn.mpg.de/staff/abrunthaler/BeSSeL : BeSSeL (Bar andhttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/194/25https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/194/25http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/194/25https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/194/25https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/194/25http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/194/25GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/194/25/table2 (Detected sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/194/25/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/194/25/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/194/25/table2?GETtext/xml+votable180.050000true3.156969958365.85300655560.005555555555555556Cone search capability for table J/ApJS/194/25/table3 (*Undetected sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/194/25/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/194/25/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/194/25/table3?GETtext/xml+votable180.050000true5.717958363.85605560.0055555555555555564/1818 5/765 960 3515 3560 3567 3570 3588 3613 3652 3654 3656 3661 3667 3847 3852 3857 3860 3862 3864 3868 3906 3921 3945 5385 5531 5553 6090 6126 7202 7206 7207 7219 7225 7228 7278 7361 7364 7376 7383 7389 7554 7558 7561 7562 7564 7565 7566 7576 7578 7579 7601 7604 7651 7654 7661 7673 7675 7676 7678 8020 9973 10153 10609 10614 10615 6/1331 1333 1334 1335 1337 1339 1340 1341 1342 1376 1378 1428 1462 1463 1467 1469 1470 1471 1809 1812 1814 1815 1817 3039 3057 3059 3291 3309 3311 3312 3313 3314 3316 3318 3320 3671 3677 3722 3723 3724 3726 3744 3745 3748 3752 3846 3848 3849 3850 3852 3854 3872 3873 12986 12987 13243 14059 14066 14071 14072 14073 14074 14214 14218 14219 14220 14222 14237 14244 14261 14263 14272 14275 14279 14284 14285 14290 14291 14298 14304 14305 14306 14308 14309 14311 14312 14313 14314 14316 14317 14318 14343 14356 14358 14359 14360 14361 14362 14364 14366 14430 14431 14460 14461 14599 14603 14605 14606 14607 14612 14614 14615 14620 14621 14622 14628 14629 14631 14632 14640 14641 14642 14658 14659 14665 14666 14667 14682 14688 14689 14692 14694 14696 14698 14699 14700 14702 14703 14704 14737 14784 14785 15373 15384 15386 15387 15405 15412 15414 15415 15416 15417 15420 15421 15423 15425 15434 15435 15437 15444 15447 15452 15453 15454 15462 15463 15464 15465 15466 15469 15476 15477 15478 15480 15481 15494 15618 15619 15628 15636 15637 15639 15650 15659 15681 15682 15683 15689 15692 15757 15758 15759 15769 15770 15771 15774 15777 15779 15788 15794 21508 21514 21516 21518 21519 21536 21537 21539 21545 21548 21549 21550 21552 21554 21560 22116 22122 22123 22138 22209 22221 22224 22232 24185 24188 24189 24191 24277 24279 24325 24326 24353 24354 24355 24357 24366 24449 24450 24475 24476 24493 24497 24498 24499 24500 24501 24502 28800 28801 28803 28812 28814 28819 28820 28822 28823 28832 28848 28849 28851 28852 28853 28854 28872 28875 28888 28890 28891 28892 28894 28895 28896 28897 28899 28908 28909 28917 28918 28919 28920 28921 28923 28924 28925 29066 29067 29068 29070 29071 29074 29082 29104 29110 29117 29119 29162 29163 29270 29441 29460 29461 29462 29508 29510 29512 29513 29522 29523 29526 29527 29529 29531 29553 29565 29653 30210 30220 30222 30223 30238 30239 30241 30242 30243 30252 30253 30255 30268 30269 30271 30310 30311 30322 30323 30328 30330 30331 30357 30400 30401 30413 30422 30423 30424 30425 30427 30428 30430 30431 30597 30598 30599 30609 30610 30611 30614 30615 30621 30622 30623 30628 30629 30631 30640 30641 30643 30657 30664 30667 30689 30690 30691 30696 30697 30716 30718 30719 32068 32084 32086 39806 39807 39889 39891 39896 39897 39899 39901 39902 39925 40576 40578 40584 40586 40587 40590 40608 40609 40611 40616 40617 40620 40621 42350 42351 42362 42366 42433 42434 42435 42441 42445 42446 42447 42450 42451 42454 42455 42469 42481 42484 42485https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/194/25?format=asciiRadiodefaultJ/ApJS/194/25/table2Detected sourcesrecnoRecord number assigned by the VizieR team.
