This site KURUCZ.HARVARD.EDU has been moved to a more secure computer. It provides up-to-date public access to my data and programs. These are the same programs and files that I use in my research. Many bugs and problems have been corrected but there are still many more errors remaining to be found. Programs and data that I would not use myself because they are still under development are not on this computer. Many of the files are large. If they are too large for your browser, I am willing to write DVDs of those files on request and post them to you. Some files taken from Kurucz CD-ROMs 1-26 are given for historical checks although many have been replaced by new versions. Binary versions will eventually be replaced by (much larger) ASCII versions. I am willing to rewrite them in ASCII on demand. THE DATES ARE NOT RELIABLE. 13Apr2011 is the date a disk was replaced. Dates since then are dates the file was put on the web site. There can be files dating to 1979. I will attempt to recover the creation dates. Neither the programs nor data are "black boxes". You should not be using them if you do not have some understanding of the physics and of the programming in the source code.Vita and Bibliography Papers Atoms Molecules Linelists Opacities Grids of model atmospheres Sun Stars Programs CD-ROMs Temporary files
