Every ten-hour orbit... yielded a set of 2000 one-dimensional star positions covering one great circle on the sky. In the data analysis process, these results were calculated from the raw satellite data,... until enough circles are available to carry out step 2 of the three-step procedure. This involved the interconnection, and interlocking, of a large number of such circles, obtained over a period of a few months-this is referred to as the "sphere solution" step in the Hipparcos terminology.

The Hipparcos Input Catalogue was constructed as the observing programme for the European Space Agency's Hipparcos astrometry mission. The requirements of the project in terms of completeness, sky coverage, astrometric and photometric accuracy, as well as the necessary optimisation of the scientific impact, resulted in an extended effort to compile and homogenize existing data, to clarify sources and identifications and, where needed, to collect new data matching the required accuracy. This has resulted in an unprecedented catalogue of stellar data including up-to-date information on positions, proper motions, magnitudes and colours, and(whenever available) spectral types, radial velocities, multiplicity and variability information. The catalogue is complete to well-defined magnitude limits, and includes a substantial sampling of the most important stellar categories present in the solar neighbourhood beyond these limits.

CONT

DIVA operates in a revolving scanning mode with a scanning law similar to that of Hipparcos. As the observing strategy is defined with respect to the ecliptic, the number of observations per star and, consequently the distribution of the standard errors of the astrometric parameters will strongly depend on ecliptic coordinates.
