The EXOSAT database system. On-line user's guide.

The EXOSAT database system is a mission/telescope-independent on-line astronomical facility created to access and analyse data obtained by the European X-ray Astronomy Satellite, EXOSAT. Data from other orbiting observatories (e.g. Einstein and IUE) and well-known ground-based catalogues (e.g. the HST Guide Star and HD Catalogues) can also be remotely accessed using this system. The EXOSAT system has been installed at two sites in Europe (ESTEC and the University of Leicester) and one site in the USA (GSFC). This guide describes how to access and use the on-line EXOSAT database system.
