These data sets have been aggregated with Partiview as a downloadable software package titled 'Digital Universe', as featured in a cover-story article in Natural History a couple years ago ('Virtual Universe' April 2004). In fact, the data sets can be adapted (with third-party add-ons) to control globe-planetarium projection, as used at the Hayden Planetarium. Since 1998, the Office of the Director of the Hayden Planetarium (within the Department of Astrophysics, American Museum of Natural History) has underwritten the development of a shell wrapper and a series of data sets for various stellar displays including Partiview, thereby creating an extremely powerful desktop planetarium. Partiview is an interactive data visualization tool written by Stuart Levy at the National Center for Supercomputing Applications (NCSA) that enables static and animated data visualization in 3-D and can display 2-D images and 3-D polygonal models as well Partiview is a generalized software tool used in many different scientific data display applications.
