At the press conference, Reimar Lüst received the Hipparcos Input Catalogue on behalf of ESA, in the presence of members of the Hipparcos science community and ESA Hipparcos team members.
The Hipparcos Input Catalogue formed the mission's observing programme: it contained over 100 000 target stars that Hipparcos would monitor to obtain their astrometric properties. The catalogue was compiled at the Observatoire de Paris - Meudon, France, and involved the collaboration of a large number of ESA Member State scientists. The Input Catalogue Consortium (INCA), led by Catherine Turon (Observatoire de Paris - Meudon), was responsible for the production of the catalogue and included institutes from Belgium, Denmark, France, Germany, The Netherlands, Spain, Switzerland, the U.K. and the U.S.A.
