Fityk: a general-purpose peak fitting program

M. Wojdyr

Abstract: Fityk is portable, open-source software for nonlinear curve fitting and data analysis. It specializes in fitting a sum of bell-shaped functions to experimental data. In particular, it enables Pawley refinement of powder diffraction data and size-strain analysis.

Keywords: curve fitting; Pawley refinement.
