-==== Description ====
+===== cosmicPAHmfit =====
-Mfit is an infrared emission spectroscopy fitting tool written in python language.
+==== Detailed description ====
-**Mfit** has been developed to assists scientists when fitting voigts to a spectral line profile.
-Until this tool was available, it was done manually in IDL.
-Mfit has a graphical interface to select the intensity flux where we want to fit a 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 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.\\
