- | **cosmicPAHmfit** is a fitting tool for a multi-component analysis of infrared spectra. It is written in python language. | + | ==== Detailed description ==== |
- | **cosmicPAHmfit** 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). | + | 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.\\ |
