Beginning of ReadMe : I/197A Tycho Input Catalogue, Revised version (Egret+ 1992) ================================================================================ The Tycho Input Catalogue. Cross-matching the Guide Star Catalog with the Hipparcos INCA Data Base Egret D., Didelon P., McLean B.J., Russell J.L., Turon C. <Astron. Astrophys. 258, 217, (1992)> =1992A&A...258..217E ================================================================================ ADC_Keywords: Positional data ; Photometry Mission_Name: Hipparcos Description: A 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).
