That are executed by the engine in the libfityk library. Translates the users actions to text a sequence of Fityk commands The way typical for modern computer programs and the interface 2) is written using theĬross-platform wxWidgets library. Particular, the interface simplifies the Pawley refinement of powderįityk has two user interfaces: a graphical one and a text-based one.īoth are built on top of the libfityk library (Fig. To perform the most common tasks without learning the language. Operations, but also comes with a graphical interface that allows users
FITYK PEAK ANALYSIS SOFTWARE
The software has its own mini-language, used to perform all Using one of the three fitting methods implemented in the program. When the model is prepared, it can be refined The diffraction pattern can be bound with the radiation wavelengthĪnd lattice parameters. The parameters of the component functions can beĬonstrained by any equality constraints, e.g.
X correction, the function that describes errors on the measured x Pearson VII or Voigt), polynomials and other The underlying idea of Fityk is to let the user build a model (aįunction that is to be fitted to the data) from components such as bell. Refinement procedure or introduce a custom data analysis scheme. While this is not an advantage in routineĪnalysis, the flexibility is important when one wants to modify the Luminescence and photoelectron spectroscopy, infrared and Raman Powder diffraction, Fityk is used in chromatography, photo. On using the software for analysis of powder diffraction data. The possibility of quantifying selected parameters. One of the well known iterative algorithms, such as the Levenbergįityk can analyze different types of experimental data providing The data by minimizing the weighted sum of squared residuals, using Usually a mathematical model is fitted to Similar refinement is used in many otherĮxperimental techniques. Set of parameters that provide the best fit of a mathematical function
Refinement, are optimization procedures that serve for derivation of a Pawley (1981) and Le Bail (Le Bail et al., 1988) whole profile Popular methods of powder pattern analysis, such as Rietveld (1969), In particular, it enables Pawley refinement of powder diffraction data and It specializes in fitting a sum of bell-shaped functions to experimentalĭata. Correspondence is portable, open-source software for nonlinear curve fitting and dataĪnalysis.
