The HYG Database

The current version of the database is now hosted at Github as well as here.

The HYG database (v3.0) is a compilation of interesting (to me, anyway) stellar data from a variety of catalogs. It is useful for background information on all sorts of data: star names, positions, brightnesses, distances, and spectrum information. It also powers the charts elsewhere on this site.
