I can’t recommend  LMFIT in python enough  (or Larch - never used it mind, but see no reason why I haven’t).

Its well documented, easy to use and, best of all, its FREE!  :)

Hi Matthew,

WinXAS, (Commercial program by Thorsten Ressler) does possess the capabilities you are seeking
but it costs E$200 for an academic/gov't license.
