cds-question@unistra.frmultiple-starsvisible-astronomytrigonometric-parallaxproper-motionsWe present improved Hipparcos astrometry for 257 Hipparcos stars, resolved into 342 components. For 64 of the stars no astrometry was obtained in the Hipparcos Catalogue, while for the remaining stars additional components have been added by this solution or the positions have been revised considerably. We have used the published Hipparcos transit data for the new solutions, together with results from the second reduction of the Tycho data for defining better initial values.2000A&AS..144...45Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+AS/144/45CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/239 : The Hipparcos and Tycho Catalogues (ESA 1997)I/259 : The Tycho-2 Catalogue (Hog+ 2000)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+AS/144/45https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+AS/144/45http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+AS/144/45https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+AS/144/45https://vizier.iucaa.in/viz-bin/votable?-source=J/A+AS/144/45http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+AS/144/45GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+AS/144/45/table3 (Revised Hipparcos astrometry)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+AS/144/45/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/A+AS/144/45/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+AS/144/45/table3?GETtext/xml+votable180.050000true2.2374076866.456648840.0055555555555555566/1362 1682 1856 2038 2353 2505 2724 2883 3249 3507 3697 3754 4002 4206 4240 6274 6307 7018 7054 7059 7256 7878 8895 9265 9296 9324 9767 10103 10130 10370 10401 10936 11811 12041 12957 12974 13517 14036 14130 14294 14309 14456 14638 14696 14702 14785 15437 15462 17019 17239 17409 18389 18936 19022 19416 20523 20575 20806 20851 20941 21175 21439 21619 21860 21962 22024 22053 22066 22254 22602 22805 22865 23010 23344 23514 23631 23662 23985 24545 24858 24942 25365 25397 26543 26614 27518 27564 27712 27926 28645 28816 28911 29746 30006 30936 31176 31184 31281 32274 32470 32516 32679 33298 35950 36248 36308 36674 37238 37368 37502 37587 37923 37988 38317 38547 38625 38908 39675 39841 40085 40192 40582 41058 41199 41340 41480 41768 42031 42142 42196 42220 42318 42426 42459 42479 42538 42618 42646 42897 43042 43289 43321 43329 43339 44013 44589 44917 45236 45549 45663 45671 45673 45885 46199 46543 46679 47158 47335 47684 47848 48299 486243.5843623949537626e-19 6.298446873438916e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+AS/144/45?format=asciiOpticaldefaultJ/A+AS/144/45/table3Revised Hipparcos astrometryrecnoRecord number assigned by the VizieR team.
