-==== Description ====
+===== cosmicPAHmfit =====
-**Mfit** is a fitting tool for a multi-component analysis of infrared spectra. It is written in python language.
+==== Detailed description ====
-**Mfit** has a graphical interface to select the spectral feature for the multi-component fit using profiles that can be Lorentzian, Gaussian or  mix of them (Voigt). The tool tries to automatically adapt it over the profile but we can manually edit the voigt parameters and add multiples voigts.
+cosmicPAHmfit is a python fitting tool. It performs a multi-component fit of the selected spectral feature using pseudo-Voigt functions (linear combination of a Gaussian curve and of a Lorentzian curve modified by an asymmetry factor). It computes the area-weighed peak position and width of the feature. It has a graphical interface to select the spectral feature of interest as well as the number of components to be included in the fit.\\
