Interface to open stellar spectra and construct stellar and telluric models
Project description
ASTRA
Welcome to the repository of ASTRA (Astrophysical Spectral Tools for Retrieval & Analysis).
The main goal of this project is to standardize the handling of stellar spectra for both RV extraction tools and spectral analysis tools. In order to do so, ASTRA provides:
- Common interface to interact with stellar spectra of different state-of-the-art instruments
- Framework to construct stellar templates from data, following best practices
- Framework to mask telluric features from stellar spectra
- Implement utility methods to interpolate, normalize and smooth stellar spectra
For information on installation, usage, and contribution check the official documentation
Installation
ASTRA is currently available in python 3.11 and python 3.12, and it can be installed either through
- Pypi
pip install ASTRA-spectra
- Github
git clone git@github.com:Kamuish/ASTRA.git
cd ASTRA
pip install .
By default, ASTRA does not install Telfit as it will only be needed for the masking of the telluric features. If this is the goal, it must be installed manually.
Contribution guidelines
Management of any issues to the code, as well as external contribution is done through the github repository
