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), you can get the code and documentation using the links provided here and ignore any instructions in the older documentation (versions 10.4 and 9.5, which have not been updated) pointing to the ftp website.

If you want an old version then VPFIT10.4 is still available. The associated documentation is in vpfit10.4.pdf and rdgen10.4.pdf.

For an even older version: VPFIT9.5, with documentation in 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.
