Installation

Install the core package from PyPI:

python -m pip install qsospec

Install optional pPXF host decomposition:

python -m pip install "qsospec[host]"

For development and documentation:

git clone https://github.com/rudolffu/qsospec.git
cd qsospec
python -m pip install -e ".[dev,host,docs]"

qsospec supports Python 3.9–3.13. Scientific templates for Fe II and the Balmer pseudo-continuum are included in the package. Galactic dust maps and pPXF stellar templates are external data and must be configured separately.
