Scientific paper

Preliminary positions and magnitudes derived from the analysis of 12 weeks of observations from the Hipparcos star mappers are systematically compared with the various sources of ground-based data used in the Hipparcos Input Catalogue. These comparisons allow us to cross-check the accuracies claimed by the various sources of ground-based data and by the analysis method of star mapper data. The parameters obtained for double stars, relative position and orientation, are also compared with ground-based data.
