cds-question@unistra.frquasarsastrometryinterferometryproper-motionsWhile analyzing decades of very long baseline interferometry (VLBI) data, we detected the secular aberration drift of the extragalactic radio source proper motions caused by the rotation of the Solar System barycenter around the Galactic center. Our results agree with the predicted estimate to be 4-6 micro arcseconds per year (uas/yr) towards RA=266{deg} and DE=-29{deg}. In addition, we tried to detect the quadrupole systematics of the velocity field. The analysis method consisted of three steps. First, we analyzed geodetic and astrometric VLBI data to produce radio source coordinate time series. Second, we fitted proper motions of 555 sources with long observational histories over the period 1990-2010 to their respective coordinate time series. Finally, we fitted vector spherical harmonic components of degrees 1 and 2 to the proper motion field.2011A&A...529A..91Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/529/A91CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/251 : VLBI International Celestial Reference Frame, ICRF (Ma+, 1997)J/A+A/355/398 : Celestial Ephemeris Origin definition (Capitaine+, 2000)J/AZh/81/1032 : VLBI position measurements (Titov, 2004)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/529/A91https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/529/A91http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/529/A91https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/529/A91https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/529/A91http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/529/A91GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/529/A91/list555 (Position and proper motions of 555 quasars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/529/A91/list555?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/529/A91/list555?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/529/A91/list555?GETtext/xml+votable180.050000true1.14856452825-47.605445481236010.0055555555555555566/18 60 80 110 124 180 304 307 375-376 421 438 532 548 700 839 911 991 1084-1085 1154 1233 1509 1521 1546 1584 1616 1622 1702 1740 1782 2098 2124 2143 2158 2397 2414 2531 2564 2710 2721 2836 2867 3024 3096 3316 3675 3820 3882 3971 4054 4352 4436 4448 4695-4696 4754 4770 4820 4964 5139 5154 5163 5200 5306 5353 5371 5423 5448 5458 5546 5597 5652 5657 5693 5766 5817 5848 6033 6067 6164 6167 6193 6219 6448 6496 6507 6548 6641 6716 6751 6790 6853 6923 6948 6976 6996 7091 7148 7181 7296 7345-7346 7351 7371 7389 7472 7548 7570 7606 7623 7851 7857 7896 7969 8031 8057 8112 8123 8199 8207 8299 8345 8487 8615 8717 8729 8805 8858 8948 9075 9204 9232 9248 9258 9403 9460 9512 9545 9588 9612 9632 9655 9676 9681 9688 9711 9714 9813 9906 9976 9998 10006 10078 10163 10170 10228 10249 10352 10422 10432 10466 10524 10548 10598 10798 10803 10983 11037 11094 11216 11279 11430 11461 11639 11715 11845 11880 12173 12218 12241 12301 12475 12505 12580 12599 12611 12844 12851 12971 13156 13213 13230 13352 13545 13693 13722 13792 13927 14150 14338 14348 14520 14737 14820 14842 14854 15023 15036 15286 15494 15536 15819 15852 15936 16027 16049 16057 16059 16093 16113 16185 16261 16281 16298 16301-16302 16592 16676 16720 16962 17019 17110 17184 17188 17215 17351 17414 17516 17541 17579 17734 17791 17857 17909 17937 18002 18022 18037 18084 18214 18271 18378 18457 18545 18561 18624 18661 18669 18718 18755 18871 18907 19088 19166 19177 19223 19271 19370 19398 19523 19567 19609 19629 19831 19872 19882 19918 19970 20144 20213 20468 20476 20657 20725 20888 20935 21012 21049 21117 21121 21163 21358 21437 21508 21564 21758 21768 21924 21935 21960 21968 21972 21990 22363 22375 22396 22433 22501 22558 22658-22659 22917 22943 22950 22965 22993 23014 23099 23121 23127 23306 23335 23383 23416 23478 23761 23786 23805 23882 24099 24116 24123 24257 24335 24453 24568 24571 24608 24734 24809 24845 24941 25016 25036 25196 25255-25256 25302 25428 25501 25503 25630 25677 25742 25864 25990 26000 26083 26100 26115 26303 26363 26550 26624 26946 26966 26983 27060 27310 27322 27423 27433 27436 27446 27514 27583 27595 27765 27773 27909 27926 28042 28167 28208 28339 28383 28453-28454 28463 28479 28492 28517 28628 28799 29016 29218 29384 29570 29675 29714 29795 29963 30527 30542 31176 31190 31211 31334 31355 31391 31430 31451 31520 31529 31535 31559 31664 31857 31894 31930 32068 32311 32325 32594 32660 32764 32841 32916 33043 33549 33560 33626 33684 33825 33827 33829 33833 34013 34038 34099 34123 34264 34428 34461 34517 34571-34572 34699 34870 34931 35294 35370 35440 35651 35786 35801 36100 36151 36155 36188 36417 36554 36863 36941 37201 37217 37474 37480 37994 38189 38277 38579 38734 38763 39377 39577 39672 39848 40344 40527 40692 40730 41059 41275 41310 41511 42853 42883 42901 42980 43366 43399 43822 43936 44034 44043 44144 44147 44247 44310 44555 44614 44661 44724 44776 44805 44832 44899 44908 45011 45110 45158 45162 45178 45196 45393 45614 45621 45795 46055 46251 46310 46337 46373 46459 46588 46764 46921 46964 47014 47016 47080 47106 47268 47375 47534 47540 47941 48023 48123 48142 48320 48362 48589 48595 48610 48798 48846 48985https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/529/A91?format=asciiOpticaldefaultJ/A+A/529/A91/list555Position and proper motions of 555 quasarsrecnoRecord number assigned by the VizieR team.
