Abstract
A Tycho Input Catalogue of three million stars brighter than V = 12,1 has been produced for the needs of the Tycho data analysis. This catalog results from the cross-matching of a subset of the Hubble Space Telescope Guide Star Catalog with the Hipparcos INCA Data Base. The cross-matching procedure is explained and statistics about the magnitude distribution and errors of the resulting catalog are given.
