cds-question@unistra.frproper-motionsAbsolute proper motions of 48 Hipparcos stars in nine fields distributed over the northern hemisphere are presented. The proper motions have been recently used as part of the Bonn program for the extragalactic link of the Hipparcos proper motion system. We describe methods which have led to the absolute proper motions of the major part of the Bonn fields for the link. For six fields the extragalactic calibration was achieved using the bright quasar in the centre of the field. In addition, data of three fields of globular clusters were included. For these fields the link to an extragalactic reference system was performed by stars, whose absolute proper motions with respect to galaxies were determined on plates of the Lick astrograph. In addition, we used for the link in one field plates from the ESO Schmidt telescope in combination with measurements from glass copies of the Palomar Sky Survey. The accuracy of a single proper motion is of the order of 2 to 3mas/a for each coordinate.1997A&AS..124..157Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+AS/124/157CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+AS/124/157https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+AS/124/157http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+AS/124/157https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+AS/124/157https://vizier.iucaa.in/viz-bin/votable?-source=J/A+AS/124/157http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+AS/124/157GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+AS/124/157/table2 (48 stars with absolute proper motion for the calibration of the Hipparcos proper motion system (Equinox J2000, Epoch 1950))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+AS/124/157/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+AS/124/157/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+AS/124/157/table2?GETtext/xml+votable180.050000true113.8520166717.383277780.0055555555555555565/7016 6/4694-4695 4768 4770 4866 8954 10321 10323 16057-16059 16295 16312 19089 19091 22495 22517 22519 26270 26293-26294 28072-28073 31112-31113 31115 31137https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+AS/124/157?format=asciiOpticaldefaultJ/A+AS/124/157/table248 stars with absolute proper motion for the calibration of the Hipparcos proper motion system (Equinox J2000, Epoch 1950)recnoRecord number assigned by the VizieR team.
