fityk:
fityk: Fityk is a program for data processing and nonlinear curve fitting.
fityk: Primarily used:
fityk: - by scientists who analyze data from powder diffraction,
fityk: chromatography, photoluminescence and photoelectron spectroscopy,
fityk: infrared and Raman spectroscopy, and other experimental techniques;
fityk: - to fit peaks -- bell-shaped functions (Gaussian, Lorentzian, Voigt,
fityk: Pearson VII, bifurcated Gaussian, EMG, Doniach-Sunjic, etc.);
fityk: but it is suitable for fitting any curve to 2D (x,y) data.
