Celestia 2000 is a CD-ROM containing the Hipparcos and Tycho Catalogues (main catalogues and some annexes) in compressed `bit-optimised' binary format, along with dedicated software permitting interrogation, sample construction and information display. The mission results are complemented by additional data taken from an updated version of the Hipparcos Input Catalogue or from the SIMBAD database. Interrogating facilities: the data are available per star, through windows displaying all data available in one catalogue (HIP, TYC or HIC) or annex (Double and Multiple Systems Annex, Parts C, G, O, V, and X; Variability Annex, Section 1 and 2), including notes and references, identification charts and variable stars light curves, if any. Sampling facilities: samples can be defined using data or identifiers from the Hipparcos and Tycho Catalogues, or from the Hipparcos Input Catalogue. A total of 135 parameters (62 for HIP, 52 for TYC, and 21 for HIC and updates) can be used to define a criterion. Once a sample has been selected, it is then possible: to list the identifiers of the selected stars; to display the HIP or TYC window by clicking on the selected identifier; to draw a global or a local sky map for the selected sample; to prepare a file for external use, with data from HIP and/or TYC and/or HIC. Mapping facilities: The global or local sky distribution of HIP and/or TYC stars can be displayed in various ways.
