The current level of development of the spectra analysis software Unifit for Windows is presented and evaluated by checking with test spectra. The program is characterized and the correctness of the numerical routines is demonstrated for the particular cases of the Shirley type background model and the Gaussian–Lorentzian product model functions. Different approaches to an optimum fit result are suggested. A convenient analysis of the assessment of the peak fit procedure is proposed. All results are presented in tabular form too, to make the data more comprehensible.
