In summary, the basic mode of SpectraFit should allow the user to fit spectra with a minimum of effort and to get a quick overview of the fit results. One of the main focuses is to provide the user with a tool that is easy to use and understand because the complexity of the underlying fitting package is hidden from the user. Therefore, the user input is kept as simple as possible, and the output is provided in a graphical and structured way. As part of the support of its simple philosophy, the following distribution models are delivered by default: Lorentzian, Gaussian, Pseudo-Voigt, Voigt, exponential function, step functions, and cumulative functions.
