Absorption line fitting implemented in Python.
If you use this software, please cite my paper on arXiv. Please let me know that you're using VoigtFit by filling in this short form. This way I can keep you updated with critical updates.
Python version >3.6 (tested on 3.6 - 3.9 so far).
VoigtFit depends on matplotlib, numpy==1.20.3, scipy, h5py, astropy, lmfit, and numba==0.55.0.
You can install these using your favorite Python package manager such as
conda or pip.
If you encounter issues with the installation of h5py make sure that you have the HDF5 library installed. If you use Homebrew as a package manager you can try this fix [following stackoverflow]:
brew install hdf5 export HDF5_DIR="$(brew --prefix hdf5)" pip install --no-binary=h5py h5py
If you encounter issues with the installation of numba (happened for me on Mac M1 architecture), try the following:
arch -arm64 brew install llvm@11 LLVM_CONFIG="/opt/homebrew/Cellar/llvm@11/11.1.0_4/bin/llvm-config" arch -arm64 pip install llvmlite
before installing numba.
The easiest way to install the most recent stable version of VoigtFit is
using pip:
pip install VoigtFit
If you encounter the following AttributeError when attempting to install via pip:
AttributeError: 'NoneType' object has no attribute 'splitlines'
Try running pip with the --upgrade option:
pip install --upgrade VoigtFit
Alternatively, you can get the latest version of the source by cloning the git repository:
git clone https://github.com/jkrogager/VoigtFit.git
Once you've downloaded the source, you can navigate into the root source directory and run:
python setup.py install
If you encounter any problems, do not hesitate to raise an issue here.
