The Fifth Fundamental Catalog of Stars (FK5), Parts I and II, is a compilation of data on more than 4500 stars. The catalog contains positions, errors in positions, proper motions, and characteristics such as magnitudes, spectral types, parallaxes, and radial velocities. There are also cross-references to the identities of stars in other catalogs. It was compiled by researchers at the Astronomisches Rechen-Institut in Heidelberg.

Positions are given in terms of right ascension and declination. Projections and Parameters in the Concepts section of the Mapping Toolbox™ documentation shows how to convert these to latitude and longitude for display by the toolbox.
The Fifth Fundamental Catalog of Stars (FK5), Parts I and II data and documentation are available over the Internet by anonymous ftp.
