PyKOALA

A multi-instrument tool for reducing Integral Field Spectroscopic Data

---

PyKOALA is an innovative Python-based library designed to provide a robust and flexible framework for Integral Field Spectroscopy (IFS) data reduction. By addressing the complexities of transforming raw measurements into scientifically valuable spectra, PyKOALA simplifies the data reduction pipeline while remaining instrument-agnostic and user-friendly.

Installation

Creating a virtual environment (recommended)

To avoid dependency conflicts, we recommend the use of virtual environments for the installation of PyKOALA. For example, a simple way to setup a python environment is by using the venv module:

python3 -m venv venv_pykoala # common conventions are .venv or venv

To activate the environment, use:

source venv_koala/bin/activate

To stop using the environment:

deactivate

Installing from pypi

Every release of PyKOALA is automatically avaialable through PyPI:

python3 -m pip install pykoala-ifs

You can check this link for a complete list of previous releases.

Installing from the source repository

PyKOALA can be installed by cloning this repository using:

git clone https://github.com/pykoala/pykoala.git

Then users can install all required packages with:

cd path/to/pykoala
python3 -m pip install -r requirements.txt  # Install the dependencies
python3 -m pip install .  # Install pykoala

For more further instructions about the installation and virtual environtment setup, check the quick-start documentation.
