Description

This is the users manual for the Hipparcos interactive data access software. The Hipparcos data access software provides tools to interrogate the Hipparcos data from overall statistics to the solution details for individual stars. It grew from the need to be able to interact directly with the data in the Hipparcos catalogue, being able to display relevant data in such a way that details at any resolution can be made visible, from overall statistics and distributions down to the details of individual stars. It also provides access to large sets of ground-based photometric and spectroscopic data, where the Hipparcos information on in particular parallaxes can give more detailed insight in colour-index dependencies. To provide further insight into the Hipparcos data, the most relevant calibration data are also made available.
