+ | 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.\\ |
