PySME
Spectroscopy Made Easy (SME) is a software tool that fits an observed spectrum of a star with a model spectrum. Since its initial release in 1996, SME has been a suite of IDL routines that call a dynamically linked library, which is compiled from C++ and fortran. This classic IDL version of SME is available for download.
PySME includes high-performance adaptive synthesis for wide and line-rich spectra in both plane-parallel and spherical atmospheres.
In 2018, we began began reimplmenting the IDL part of SME in python 3, adopting an object oriented paradigm and continuous itegration practices (code repository, build automation, self-testing, frequent builds).
Installation
Stable release (recommended):
pip install pysme-astro
On macOS arm64, pip will use a pre-built wheel when one matches your Python
and macOS version. If no compatible wheel is available, pip falls back to a
source build. In that case, install the local build toolchain first:
brew install gcc cmake ninja
Install latest source from GitHub:
git clone --recurse-submodules https://github.com/SpectroscopyMadeEasy/PySME.git
cd PySME
pip install .
If you already cloned without submodules:
git submodule update --init --recursive
For full installation options (virtual environments, specific tags, uninstall), see: https://pysme-astro.readthedocs.io/en/latest/getting_started/installation.html

GUI
A GUI for PySME is available in its own repository PySME-GUI.
Windows
PySME is supported on Windows via WSL2 (install and run PySME inside the Linux subsystem).
