It is nearly complete to V=3mag except for three stellar systems. A combined astrometric solution of the Hipparcos Intermediate Astrometry Data and two dedicated ground-based campaigns in 2013-2020 is the basis for this catalog. The astrometric parameters for each star include position coordinates, parallax, and proper motion components, and their covariances on the Hipparcos mean epoch 1991.25. 64% of the catalog are flagged as known or suspected double or binary stars. UBSC lists 68 stars missing in Gaia EDR3 and another 114 stars without Gaia parallaxes or proper motions. The formal precision achieved for proper motions is comparable to that of Gaia. 2022AJ....164...36Z https://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/164/36 Catalog Research IsServedBy TAP VizieR generic service IsServedBy Conesearch service related-to I/239 : The Hipparcos and Tycho Catalogues (ESA 1997) I/345 : Gaia DR2 (Gaia Collaboration, 2018) J/A+A/397/997 : Hipparcos red stars (Platais+, 2003) J/A+A/399/1167 : Hipparcos Variability-Induced Movers (Pourbaix+, 2003) J/AJ/129/2420 : Proper motion derivatives of binaries (Makarov+, 2005) J/AJ/131/2967 : {alpha} Persei open cluster members (Makarov+, 2006) J/A+A/623/A72 : Binarity of Hipparcos stars Gaia pm anomaly (Kervella+, 2019) J/ApJS/254/42 : Hipparcos-Gaia (EDR3) Catalog of Accelerations (Brandt, 2021) J/AJ/163/131 : USNO-UBAD catalog of bright stars (Munn+, 2022) https://cds.unistra.fr/vizier-org/licences_vizier.html https://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/164/36 https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/164/36 http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/164/36 https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/164/36 https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/164/36 http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/164/36 GET text/xml+votable https://tapvizier.cds.unistra.fr/TAPVizieR/tap Cone search capability for table J/AJ/164/36/table2 (*The USNO Bright Star Catalog) https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/164/36/table2? https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/164/36/table2? http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/164/36/table2?
