cds-question@unistra.froptical-observationcatalogsastrometryvery-long-baseline-interferometryWe use very long baseline interferometry data obtained between mid-1995 and the end of 2002 May together with older data to extend and revise the International Celestial Reference Frame (ICRF). Revised positions of ICRF candidate and "other" sources, based on inclusion of the additional data, are presented. Positions, in the frame of the ICRF, for an additional 109 new sources are also presented. All but four of the new sources are located north of {delta}=-30{deg}. Positions of the ICRF defining sources remain unchanged. We present a summary of current astrometric and geodetic observing programs and discuss the evolution and future of the ICRF.2004AJ....127.3587Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/127/3587CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/251 : VLBI International Celestial Reference Frame (ICRF) (Ma+, 1997)I/218 : New Reference Frame defined by Extragalactic Radio SourceI/239 : The Hipparcos and Tycho Catalogues (ESA 1997)http://hpiers.obspm.fr/webiers/results/icrf/README.html : ICRF Home Pagehttp://aa.usno.navy.mil/AA/data/docs/ICRS_links.html : ICRS at USNOhttp://hpiers.obspm.fr/webiers/results/icrf/Updating.html : Updatinghttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/127/3587https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/127/3587http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/127/3587https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/127/3587https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/127/3587http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/127/3587GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/127/3587/icrf (All ICRF positions (tables 1, 2 and 3 of the paper))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/127/3587/icrf?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/127/3587/icrf?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/127/3587/icrf?GETtext/xml+votable180.050000true9.91508137514.199321258330.0055555555555555566/18 124 198 307 375 421 438 532 548 556 593 839 911 991 1038 1084-1085 1200 1233 1263 1546 1622 1701 1782 2087 2207 2214 2245 2414 2531 2564 2600 2631 2710 2867 3024 3096 3309 3316 3402 3820 3886 4436 4572 4594 4627 4685 4695 4770 4820 4866 4992 5163 5423 5458 5657-5658 5766-5767 6014 6067 6104 6377 6469 6507 6532 6686 6751 6755 6790 6824 6976 7426 7435 7472 7548 7606 7623 7642 7653 7716 7745 7851 7969 8199 8299 8521 8577 8717 8729 8773 8805 8858 8905 8915 8948 9016 9125 9142 9219 9232 9347 9442 9460 9536 9545 9612 9632-9633 9655 9681 9688 9714 9720 9723 9837 9998 10006 10078 10321 10422 10432 10435 10440 10463 10466 10501 10511 10519 10524 10548 10561 10598 10802-10803 11027 11206 11216 11226 11407 11461 12047 12173 12241 12352 12400 12505 12547 12619 12842 12971 12987 13410 13496 13545 13693 13722 13789 13792 13927 14338 14348 14455 14520 14608 14632 14634 14737 14744 14820 14908 15036 15266 15373 15852 15936 15947 16059 16093 16281 16298 16302 16592 16962 17110 17184 17188 17215 17351 17414 17529 17541 17579 17734 17791 17909 18002 18022 18035 18037 18084 18214 18239 18242 18259 18271 18378 18438 18457 18506 18545 18624 18661 18669 18718 18755 18871 18907 19088 19101 19166 19177 19191 19197 19370 19398 19523 19609 19629 19748 20099 20144 20358 20476 20500 20503 21012 21049 21117 21121 21163 21266 21358 21564 21768 21924 21935 21960 21968 21990 22375 22396 22433 22658-22659 22917 22943 23022 23099 23121 23197 23223 23242 23323 23333 23383 23691 23761 23786 23805 23855 23882 24003 24084 24326 24349 24357 24571 24608 24845 25016 25083 25196 25255 25302 25428 25493 25503 25630 25647 25677 25742 25864 25990 26000 26083 26115 26131 26244 26292 26297 26301 26491 26550 26769 26816 26900 26966 27060 27220 27310 27322 27446 27464 27466 27583 27595 27714 27765 27773 28184 28249 28383 28479 28492 28495 28643 28799 28897 29016 29110 29218 29522 29570 29675 29714 29795 30507 30527 30609 30657 30706 31211 31334 31355 31430 31451 31529 31559 31857 31894 31998 32035 32066 32247 32311 32660 32764 32948 32961 33010 33048 33057 33180 33626 33684 33816 33829 33833 33973 34013 34099 34123 34210 34330 34428 34461 34517 34534 34675 34699 34871 35079 35249 35370 35440 35482 35491 35651 35786 36155 36417 36554 36785 36877 37064 37217 37474 37819 37919 37994 38128 38189 38277 38383 38416 38474 38579 38734 38763 39181 39235 39241 39447 39489 39557 39672 39695 39733 39848 40060 40344 40479 40730 40990 41072 41088 41578 41665 41669 42060 42249 42366 42571 42853 42901 42980 43195 43257 43262 43366 43399 43417 43566 43628 43694 43822 43936 44034 44043 44147 44247 44502 44614 44658 44661 44724 44776 44805 44899 44908 45011 45178 45393 45409 45446 45612 45614 45621 45763 45774 45784 45795 46174 46337 46394 46562 46709 46762 46851 46921 46931 46964 47014 47016 47080 47107 47255 47268 47375 47534 47747 48023 48123 48142 48228 48362 48595 48610 48798 48846 48965https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/127/3587?format=asciiOpticalRadiodefaultJ/AJ/127/3587/icrfAll ICRF positions (tables 1, 2 and 3 of the paper)recnoRecord number assigned by the VizieR team.
