+===== cosmicPAHmfit =====
-**cosmicPAHmfit** is a fitting tool for a multi-component analysis of infrared spectra. It is written in python language.
+==== Detailed description ====
-**cosmicPAHmfit** 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 performs the fit based on the number of components that are defined by the user.
+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 possibly modified by an asymmetry factor). 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. For each component, it provides the evolution of the position, width (FWHM) and integrated intensity as a function of temperature.\\
