The correct reference for the catalogue is as follows:
ESA, 1997, The Hipparcos and Tycho Catalogues, ESA SP-1200
The Center for Astrophysics version of the catalog is in the local binary format and has had the proper motion added from the epoch of observation, 1991.25, to 2000.0. In addition to the Bt and Vt magnitudes, parallax and parallax error in milliarcseconds are given for each star. As of now, only a searchable RA-sorted version of the catalog is being used, as code has not yet been written to extract stars by their numbers. The numbers increase with right ascension of the star from the Hipparcos Input Catalog. The star's RA order has changed slightly due to better-known proper motions, so the numbers are no longer monotonically increasing.
The Hipparcos Catalogue can be searched by
ship (which calls
and plotted by skymap.
It is available here in a gzipped file, hipparcos.tar.gz, in Sun/Mac byte order, which can be read with STAR and SCAT on machines with either byte order.
The Hipparcos Input Catalog contains more stars, but the proper motions are not as good and the photometry is not as consistent. hipinput, sorted by ID number, is in J2000 coordinates. It is used by the program scat when the Hipparcos Input Catalog number is known and position, magnitude, and/or spectral type information is desired.
hipinputra is sorted by J2000 right ascension.
This version is used for fast searches, at least away from the
poles, by the program scat
and for plotting by skymap.
Both files are available here in a gzipped file, hipinput.TAR.gz, in Sun/Mac byte order, which can be read with STAR and SCAT on machines with either byte order.
