GFit is a highly interactive program for Windows to perform the
basic scientific task of determining peak positions and intensities in
an experimental spectrum. GFit is written for Win XP but a simple
work-around for later versions can be found here.
GFit performs a weighted non-linear
least-squares fit of a sum of Gaussian, Lorentzian
or Voigt profiles to an experimental spectrum under manual
supervision. Also included is the possibility to handle
several input materials simultaneously, or to work efficiently
through a set of consecutively numbered files. You may also
overlay a calculated spectrum on the experimental data.
supports 14 input file formats: different formatted ASCII
files including the general column-oriented Excel output (.csv), a binary direct access format, some CCD camera
formats (P.I. and Photometrics) and the general image formats
FITS and bit maps.
GFit may be used to create high quality plots
of moderate complexity for direct printing or saved as a postscript
