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

Installation

pip install cosmicPAHmfit
python3 -m cosmicPAHmfit

-It is recommanded to use a virtual environment copy/paste The pyenv version can be above 3.12 if preferred. (On windows pyenv is not working, proceed to installation of a compatible python (3.12-3.15). A virtual environment is not mandatory.)

pyenv install 3.12.3
pyenv virtualenv 3.12.3 venv
pyenv activate venv

If the previous commands do not work. Install pyenv: -On Linux To create a pyenv virtualenv for running an other python in a venv run the following blocks (copy/paste);

curl https://pyenv.run | bash
echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.bashrc
echo '[[ -d $PYENV_ROOT/bin ]] && export PATH="$PYENV_ROOT/bin:$PATH"' >> ~/.bashrc
echo 'eval "$(pyenv init -)"' >> ~/.bashrc
exec "$SHELL"
sudo apt-get update; sudo apt-get install -y build-essential libssl-dev zlib1g-dev libbz2-dev \
libreadline-dev libsqlite3-dev wget curl llvm libncurses5-dev libncursesw5-dev \
xz-utils tk-dev libffi-dev liblzma-dev python3-openssl git
echo 'eval "$(pyenv virtualenv-init -)"' >> ~/.bashrc

-On MAC if the previous install doesn't work copy/paste the following:

brew install pyenv-virtualenv
export PYENV_ROOT="$HOME/.pyenv"
command -v pyenv >/dev/null || export PATH="$PYENV_ROOT/bin:$PATH"
eval "$(pyenv init --path)"
eval "$(pyenv init -)"

Usage

Run the following line

pyenv activate venv; python3 -m cosmicPAHmfit

to exit the pyenv venv you must use:

pyenv deactivate

If (venv) appears in the terminal, the pyenv venv is running. To run the application you can use directly:

python3 -m cosmicPAHmfit
