About Robert L. Kurucz
This site provides public access to Robert L. Kurucz's research data and programs, including files on atoms, molecules, linelists, opacities, grids of model atmospheres, the Sun and stars, papers, and files from Kurucz CD-ROMs 1-26. The files are the same programs and data used in his research, with many bugs corrected. Many errors remain to be found, file dates are not reliable, and many files are large. Programs still under development are not included, and the programs and data require understanding of the physics and programming in the source code.
