We have observed 267 VLBI source candidates selected from existing radio surveys and have detected 93 sources at a signal-to-noise ratio larger than 5. While 42 of the 93 detected sources had already been detected with VLBI at relatively lower frequency (typically 2 to 8GHz), the remaining 51 are found to be new VLBI sources detected for the first time. These are located within |b|<=5{deg}, and have a large number of galactic maser sources around them. Thus, they are potential candidates for phase reference sources for VLBI Exploration of Radio Astrometry (VERA), which is the first VLBI array dedicated to phase-referencing VLBI astrometry aimed at measuring the parallax and proper motion of maser sources in the whole Galaxy.2000PASJ...52..631Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/PASJ/52/631CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/251 : VLBI International Celestial Reference Frame (ICRF) (Ma+, 1997)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/PASJ/52/631https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/PASJ/52/631http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/PASJ/52/631https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/PASJ/52/631https://vizier.iucaa.in/viz-bin/votable?-source=J/PASJ/52/631http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/PASJ/52/631GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/PASJ/52/631/table1 (List of 284 VLBI source candidates.)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/PASJ/52/631/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/PASJ/52/631/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/PASJ/52/631/table1?GETtext/xml+votable180.050000true0.280833360.85694440.0055555555555555566/1286 1309 1312 1327 1329 1342 1356 1423 1435 1447 1450 1454 1460 1466 1469 1483 1749 1782 1787 1801 1812 1817 1831 1852 1956 1964 1970 3022 3024 3034 3050 3052 3060 3063 3141 3151 3158 3162 3170 3183 3186 3272 3308-3309 3316 3318 3330 3595 3598 3613 3644 3652 3654 3656 3659 3666 3712 3718 3737 3742 3749 3752 3761 12975 12987 13033 13038 13047 13222 13224 13230 13292 14009 14042 14068 14234 14280 14282-14283 14291 14304 14307 14314 14333 14338 14348 14356 14359 14384-14385 14393 14400 14408 14413 14432 14603 14605 14608 14618 14620 14622 14624 14637 14718 14737 15369 15389 15424 15429 15438 15463 15473-15474 15477 15639 15641 15652 15684 15690 15713 20823 20825 20830 20853 20861 21508 21532 21537 21562 21564 21632 21634 21653-21654 21675 21678 21683 21704 21707 22033-22034 22047 22066 22070-22071 22078 22080-22081 22083 22085 22095 22106-22107 22116 22121 22173 22199 22219 22246 22256 22271 23573 23623 23632 23637 23644 23678 23761 23765 23805 23820 23848 23850 23855 23943 23946 23961 23966 23978 23986 24150 24326 24335 24346 24349 24353 24426 24453 24464 24472 24477 24506 24511 24554 28870 28888 28897 28915 28918 28920 29056 29063 29091 29094 29101 29110 29114 29174 29176 29207 29271 29273 29442 29444 29452 29460 29515 29519 29522-29523 29535 29541 29558 29653 29867 30210 30244 30248 30251 30256 30258-30259 30262 30314 30323 30406 30436 30506-30507 30511 30527 30609 30669 30683 30695 30701 30705-30706 30711 30715 32017 32066 32068 32070 32087 39884 39886 39888 39894 39920 39923-39924 40582 40613 40615 40621 40623 40635https://cdsarc.cds.unistra.fr/viz-bin/moc/J/PASJ/52/631?format=asciiRadiodefaultJ/PASJ/52/631/table1List of 284 VLBI source candidates.Note[IVM ] Note (2)meta.notecharrecnoRecord number assigned by the VizieR team.
