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. User manual is available through User manuel Full code is available from gitlab

Use the following document to site this application: How to cite cosmicPAHmfit

It is recommended to use a python virtual environnement. For example by using pyenv The python version must be 3.12 or higher. 3.12 to 3.15 are tested and work correctly. Within the virtual environnement use the following command to install the application:

pip install cosmicPAHmfit

And either one to run the application:

python3 -m cosmicPAHmfit

Or

cosmicPAHmfit

The installation is detailed in the README.md
