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.

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
