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 standirdize 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
