The variable star work included the participation of the AAVSO staff (USA), AFOEV, CRIM and INRIA (France).

The ESA Hipparcos Scientific Selection Committee

The proposals submitted by the scientific community were reviewed by a peer committee, established under the guidance of the ESA Astronomy Working Group. The composition was as follows:

This Scientific Selection Committee met on three occasions. At the first meeting, general priorities were assigned to proposals or subsets of the proposals.

At the second meeting, after the results of the first round of simulations had been made by the INCA Consortium, and after proposers had been invited to comment on the general recommendations of the Committee, the preliminary recommendations were reviewed. Members of the INCA Consortium presented the simulation results, and the Selection Committee recommended topics for further study.

At the third meeting of the Selection Committee, the INCA Consortium made a detailed presentation of the results of the selection process, showing the extent to which various proposals and categories of proposals had been included in the Input Catalogue.

The various meetings of the Selection Committee were also attended by the leaders of the Hipparcos Data Reduction Consortia, who were able to provide advice on technical aspects of the data analysis which might impact on considerations of the Input Catalogue compilation.

In June 1988, the INCA Consortium distributed, to each of the proposal Principal Investigators, a listing of the stars from the original proposal finally contained in the Input Catalogue. A second opportunity was provided for comments on the listing. In this way, since the observing programme for the Hipparcos satellite would not be changed throughout the mission, proposers were given the opportunity to comment on the selection, achieved amongst the stars they had proposed, until just a few months before the satellite's launch.

Scientific Proposals received by ESA

The following table lists the proposals received by the European
Space Agency as a result of the Invitation for Proposals issued in
1982. For each proposal, the Principal Investigator, institute,
and title of the proposed investigation are listed.

The Royal Greenwich Observatory and the Hamburg Observatory are acknowledged for the use of the CPC2 Catalogue prior to publication, as a joint contribution from these observatories.

Many observers, in various observatories, undertook extensive measurement programmes related to the Hipparcos Input Catalogue preparation (astrometric observations and measurements, photoelectric observations, special observations of double and multiple systems). The work performed and the support they received from their respective institutions is gratefully acknowledged. The support of the management and staff of the European Southern Observatory (ESO), of the Carlsberg Automatic Meridian Circle (operated jointly by the Copenhagen University Observatory, the Royal Greenwich Observatory and the Real Instituto y Observatorio de la Armada en San Fernando) and of the Bordeaux automatic meridian circle, is especially acknowledged.

For the work on variable stars, and especially large-amplitude variable stars requiring the use of ephemerides for their efficient observation by Hipparcos, acknowledgements are due to the AAVSO and AFOEV staff and observers, to O. Gascuel and J. Quinqueton of CRIM (Centre de Recherches en Informatique de Montpellier), to E. Diday of INRIA (Institut National de Recherche en Informatique et Automatique), and especially to A.

The INCA Consortium acknowledges the careful work of reviewing the astronomical proposals submitted to ESA by the Scientific Selection Committee and especially to the Committee's Chairman, Professor A. Blaauw, for his enthusiastic involvement in the work of the Consortium.

The staff of the ESTEC Hipparcos Project Team (under Project Managers L. Emiliani and H. Hassan), in particular M. Schuyer, R.D. Wills, S. Vaghi and R. Bonnefoy, are thanked for the many helpful exchanges throughout the preparation of the Hipparcos Input Catalogue. The staff of the ESA Operations Centre (ESOC), and in particular A. Schütz, were responsible for the implementation of the Hipparcos Input Catalogue, and their work under the Ground Segment Manager, J. van der Ha, and the Spacecraft Operations Manager, D. Heger, was an important contribution to the proper functioning of the Hipparcos Input Catalogue after the satellite launch.

The INCA Steering Committee, on behalf of the entire INCA Consortium, would like to use this opportunity to give recognition to the impetus given to the Hipparcos project in its early phases by the late Professor W. Fricke, and to the effective support he brought to the work of preparation of the Input Catalogue.

The INCA Team Leader wants to highlight her deep appreciation for the dedication shown by the Hipparcos Project Scientist in ESA, Dr M.A.C. Perryman, and in particular for his unremitting and stimulating interest in all parts of the work performed in the INCA Consortium and of all its connections with other parts of the Hipparcos work.
