The Voigt profile fitting program, VPFIT, documentation contains instructions on how to download the code, and set it up. Since the old ftp method may not work much longer (if it still does), the best way of getting the code and documentation is to use the use the links provided here and ignore any instructions in the older documentation (versions 10 and 9.5, which have not been updated) pointing to the ftp website.

There is a stable version VPFIT10.2 (here as a gzipped tarfile) which has passed the standard tests so should be OK. The documentation is also available separately. Your probably won't see any notable differences from earlier, but the are some internal improvements and some added capabilities. This is the version which gets looked at if somebody reports a possible bug, or ambiguity in the documentation.As usual, it comes packed up with the current version of RDGEN, which is used to look at the data and generally sort out input for VPFIT. Hopefully the documentation adequately describes what you can do with it.

If you want an older version then VPFIT10 and VPFIT9.5 are available. The associated documentation is in vpfit10.pdf, rdgen10.pdf, vpfit9.5.pdf and rdgen9.5.pdf.

FINALLY We do our best to make sure that the program gives accurate results, and try to remove bugs etc., but of course we can't guarantee anything.  If you have any problems, inconsistencies, please e-mail to the contact address at the top. If you make any improvements yourself we'd appreciate knowing about them and possibly incorporating them.

We are very grateful to Andrew Cooke, Mike Irwin, Julian King, Joe Liske and Michael Murphy for major contributions to various parts of the program. Also, for the many people who have provided other help, improvements and suggestions for its development -- many thanks.
