Beginning of ReadMe : I/276 Tycho Double Star Catalogue (TDSC) (Fabricius+ 2002) ================================================================================ The Tycho Double Star Catalogue Fabricius C., Hog E., Makarov V.V., Mason B.D., Wycoff G.L., Urban S.E. <Astron. Astrophys. 384, 180 (2002)> =2002A&A...384..180F ================================================================================ ADC_Keywords: Stars, double and multiple Keywords: stars: binaries: visual - catalogs - astrometry Abstract: We report the discovery of 13251 visual double stars, mostly with separations between 0.3 and 1 arcsec, from a dedicated re-reduction of the Tycho data from the star mapper of the ESA Hipparcos satellite. The new doubles are combined with 18160 WDS systems identified in the Tycho-2 Catalogue, and 1220 new Tycho-2 doubles, to form the Tycho Double Star Catalogue, TDSC, a catalogue of absolute astrometry and BT, VT photometry for 66219 components of 32631 double and multiple star systems. We also include results for 32263 single components for systems unresolved in TDSC, and a supplement gives Hipparcos and Tycho-1 data for 4777 additional components. The TDS thus contains a total of 103259 entries. Cross identifications are given to WDS, HD, Hipparcos and Tycho-2
