Scientific paper

This paper describes the revised version of the Tycho Input Cagalog (TIC), TICR, which will contain positions derived from the first 12 months of the Tycho observations aboard the Hipparcos satellite, with special attention given to its proposed content, its use in the Tycho data analysis, and its other applications. The TICR will list about 500,000 stars with a positional precisions of 0.15 arcsec. Since TICR will contain ten times as many stars as does the IRS catalog and will have nearly the same accuracy, it will be a useful reference catalog for photographhic astrometry.
