Description:
The Hipparcos Input Catalogue was constructed as the observing program
for ESA's Hipparcos astrometry mission. This has resulted in a
catalogue of stellar data including up-to-date information on
positions, proper motions, magnitudes, colors, and when 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. The magnitude limits vary from 7.3 to 9 magnitudes as a
function of galactic latitude and spectral type, and there are no
stars fainter than about V = 13 mag.
118000 stars are included in the Hipparcos Input Catalogue, about half
of them have been selected within well-defined limits in V magnitude,
spectral type and galactic latitude (the "survey"), half of them
within proposed observing programs. The mean accuracies achieved, as
demonstrated by comparison with the Hipparcos results (Turon et al.
1995A&A...304...82T 1995A&A...304...82T) are 0.3 arcsec for the positions and 0.25 mag for
the Hp magnitude, with accuracies of 0.02 mag or better for more than
a third of the catalogue.
The data set consists of the main catalogue, and the first supplement
which contains more detailed information for multiple system
components. Other supplements with identification charts can be found
in the published version.
A complete description is provided, either as a LaTeX file (intro.tex),
or as a plain ascii file (intro.cat).
