Table information for 'hipparcos.main'

General

This table is available for ADQL queries and through the TAP endpoint.

Resource Description: The main result catalog from the ESA Hipparcos satellite, obtained November 1989 through March 1993. In the GAVO DC, several columns were left out and all angles are given in degrees.
