Handover of the Hipparcos input Catalogue
Reimar Lüst (ESA Director General from 1984 to 1990) receives the Hipparcos Input Catalogue from Catherine Turon (leader of the Hipparcos Input Catalogue Consortium, INCA) on 11 April 1988 at the International Hipparcos Press Conference 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. INCA 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.
