 ==== Description ==== ==== Description ====
- +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. 
-**cosmicPAHmfit** ​is a fitting tool for a multi-component ​analysis ​of infrared spectra. It is written in python language. +User manual is available through [[https://​gitlab.in2p3.fr/​ovgso/​cosmic-pah/​cosmic-pah-mfit/​-/​wikis/​uploads/​e15e6afc169937235e6060f1bdc3e518/​Manuel_d_utilisation_CosmicPAH-1.pdf|User manuel]] 
- +Full code is available from [[https://​gitlab.in2p3.fr/​ovgso/​cosmic-pah/​cosmic-pah-mfit/​cosmicPAHmfit/​|gitlab]] 
-**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.+==== Citation ====

 +[[https://​gitlab.in2p3.fr/​ovgso/​cosmic-pah/​cosmic-pah-mfit/​-/​blob/​1.1/​CITATION.cff|How to cite cosmicPAHmfit]] 
 +==== Installation ==== 
 +It is recommended to use a python virtual environnement. For example by using [[https://​github.com/​pyenv/​pyenv|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 [[https://​gitlab.in2p3.fr/​ovgso/​cosmic-pah/​cosmic-pah-mfit/​cosmicPAHmfit/​-blob/​1.1/​README.md|README.md]]
