cds-question@unistra.froptical-observationcatalogsastrometryquasarsvery-long-baseline-interferometryWe propose new estimates of the secular aberration drift, mainly due to the rotation of the Solar System about the Galactic center, based on up-to-date VLBI observations and and improved method of outlier elimination. We fit degree-2 vector spherical harmonics to extragalactic radio source proper motion field derived from geodetic VLBI observations spanning 1979-2013. We pay particular attention to the outlier elimination procedure to remove outliers from (i) radio source coordinate time series and (ii) the proper motion sample. We obtain more accurate values of the Solar system acceleration compared to those in our previous paper. The acceleration vector is oriented towards the Galactic center within ~7{deg}. The component perpendicular to the Galactic plane is statistically insignificant. We show that an insufficient cleaning of the data set can lead to strong variations in the dipole amplitude and orientation, and statistically biased results.2013A&A...559A..95Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/559/A95CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/323 : International Celestial Reference Frame 2, ICRF2 (Ma+, 2009)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/559/A95https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/559/A95http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/559/A95https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/559/A95https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/559/A95http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/559/A95GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/559/A95/list429 (Position and proper motions of 429 quasars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/559/A95/list429?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/559/A95/list429?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/559/A95/list429?GETtext/xml+votable180.050000true1.1485644-47.60544540.0055555555555555566/18 60 110 180 304 421 438 532 556 579 700 911 991 1084-1085 1154 1233 1509 1546 1622 1702 1740 2143 2158 2397 2414 2531 2564 2710 2721 2836 2867 3024 3096 3316 3820 3882 4027 4054 4572 4695-4696 4770 4820 5139 5154 5163 5306 5353 5371 5423 5448 5458 5546 5652 5657 5766-5767 5817 5848 6033 6164 6167 6193 6219 6252 6448 6496 6507 6548 6641 6716 6790 6853 6923 6948 6976 6996 7181 7296 7346 7351 7389 7472 7570 7623 7653 7709 7851 7857 7896 8031 8057 8112 8123 8199 8299 8345 8487 8717 8858 9075 9204 9232 9403 9442 9460 9545 9612 9632 9655 9676 9681 9688 9714 9723 9813 9906 9998 10006 10163 10228 10249 10321 10422 10463 10466 10548 10798 10802-10803 11216 11279 11430 11461 11715 11845 11880 12091 12173 12218 12241 12301 12352 12475 12580 12599 13156 13230 13352 13410 13496 13545 13693 13722 13927 14150 14338 14348 14520 14820 14842 14854 15023 15036 15286 15494 15819 15852 15936 16027 16059 16093 16185 16261 16281 16298 16301 16592 17019 17110 17188 17215 17351 17579 17734 17857 17909 18035 18037 18084 18214 18242 18271 18378 18506 18545 18561 18624 18661 18669 18718 18755 18907 19088 19166 19190 19370 19398 19436 19523 19609 20144 20213 20468 20476 20657 20725 20935 21121 21163 21358 21564 21758 21768 21924 21935 21960 21968 22363 22375 22396 22433 22501 22659 22917 22965 23099 23121 23127 23323 23383 23416 23478 23786 23805 23882 24084 24123 24335 24453 24571 24608 24809 24845 24941 25016 25196 25255-25256 25302 25501 25503 25630 25677 25742 25864 25990 26083 26115 26292 26303 26363 26550 26946 26983 27060 27322 27423 27446 27466 27583 27765 27773 27909 28383 28453-28454 28463 28479 28492 29016 29218 29384 29570 29675 29714 29795 30857 31176 31211 31334 31355 31391 31430 31451 31529 31535 31559 31664 31857 31894 31986 32325 32594 32660 32764 32841 32916 33043 33471 33549 33560 33570 33684 33816 33825 33827 34038 34123 34210 34264 34428 34461 34517 34571-34572 34699 34870 35079 35370 35440 35651 35801 36151 36155 36188 36554 36785 36863 36941 37190 37385 37474 37994 38277 38416 38579 38763 38802 39377 39848 40344 40527 40692 40730 40766 41059 41072 41275 41335 41511 42046 42883 42901 42980 43366 43399 43822 43936 44034 44043 44147 44247 44661 44776 44832 44908 45011 45110 45162 45178 45196 45393 45409 45614 45621 46055 46251 46310 46337 46373 46459 46588 46764 46868 46921 46964 47014 47016 47106 47268 47534 47540 47585 47941 48023 48123 48362 48589 48610 48798 48846 48965https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/559/A95?format=asciiOpticalRadiodefaultJ/A+A/559/A95/list429Position and proper motions of 429 quasarsrecnoRecord number assigned by the VizieR team.
