CASU at IoA:
Welcome to the Hipparcos/Tycho catalogue home-page!
This is the homepage for the UK Astronomy Data Centre's Hipparcos/Tycho
Catalogue service. At the time of writing the database is still under
heavy construction, although the most useful data are already available.
This includes the following:
The remaining pieces of the database will be added towards the end of the
Summer. It is not possible currently to download machine readable subsections
of the catalogues, but this will be addressed soon.
- The full Hipparcos catalogue.
- The full Tycho catalogue.
- Light-curves for variable Hipparcos stars
- Finding charts for Hipparcos stars which need them.
