The Hipparcos Catalogue

Year: 1997

Type: article

Abstract: The principal observational characteristics of the Hipparcos Catalogue, and a summary of its main astrometric and photometric properties, are presented. Median astrometric standard errors (in position, parallax, and annual proper motion) are in the range 0.7-0.9 milliarcsec (mas) for stars brighter than 9 mag at the catalogue epoch (J1991.25). The catalogue is a materialisation of the ICRS reference system, coinciding with its principal axes at the level of +/-0.6 mas, and with proper motions consistent with an inertial system at the level of +/-0.25 mas/yr. The 118218 constituent stars provide a mean sky density of similar to 3 stars deg(-2). The catalogue is available in printed and machine-readable forms.
