cds-question@unistra.frastrometryphotometryA Tycho Input Catalogue of three million stars brighter than V=12.1 has been prepared, for the needs of the Tycho mission (Hipparcos satellite). This catalogue results from the cross-matching of a subset of the Hubble Space Telescope Guide Star Catalog with the Hipparcos INCA database. References to these major catalogues, and details about the cross-matching procedures are to be found in the paper published in Astron. Astrophys. 258, 217-222 (May 1992). Among the 3,154,204 stars of the Tycho Input Catalogue, only a bit more than 1 million will appear in the final Tycho catalogue. A preliminary selection was done in the Recognition process, that was based on the first year of the satellite scientific mission (Halbwachs et al., =1994A&A...281L..25H). 1,049,971 stars were thus selected, and are flagged in this version of the Tycho Input Catalogue. The main file contains 3 154 204 records of 80 characters (total size: 256 Mbytes). It is split into four files tic1 to tic4 for easier manipulations. An annex file contains the following additional data for a subset of the stars: (a) the cross-identification with the Hipparcos Input Catalogue (117 778 records, flag 26) (b) the cross-matching with the INCA database (217 625 records, flag 20). The annex file contains 217 625 records (64 char., 14 Mbytes).1992A&A...258..217Ehttps://cdsarc.cds.unistra.fr/viz-bin/cat/I/197ACatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/196 : Hipparcos Input Catalogue, Version 2 (Turon+, 1993)I/207 : Preliminary list from Tycho observations (Halbwachs+ 1994)I/239 : Hipparcos and Tycho Catalogueshttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=I/197Ahttps://vizier.iucaa.in/viz-bin/VizieR-2?-source=I/197Ahttp://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=I/197Ahttps://vizier.cds.unistra.fr/viz-bin/votable?-source=I/197Ahttps://vizier.iucaa.in/viz-bin/votable?-source=I/197Ahttp://vizieridia.saao.ac.za/viz-bin/votable?-source=I/197AGETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table I/197A/tic (The catalogue, zones 0/37.5deg)https://vizier.cds.unistra.fr/viz-bin/conesearch/I/197A/tic?https://vizier.iucaa.in/viz-bin/conesearch/I/197A/tic?http://vizieridia.saao.ac.za/viz-bin/conesearch/I/197A/tic?GETtext/xml+votable180.050000true2.317597222.231830560.005555555555555556Hipparcos0/0 1 2 3 4 5 6 7 8 9 10 11https://cdsarc.cds.unistra.fr/viz-bin/moc/I/197A?format=asciiOpticaldefaultI/197A/ticThe catalogue, zones 0/37.5degFlag24Known variablemeta.code;src.varintFlag25Known multiple systemmeta.codeintFlag26Hipparcos Input Catalogue star (Annex file)meta.codeintFlag27CDA star (complementary astrometric data)meta.codeintrecnoRecord number assigned by the VizieR team.
