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