The blasé project (pronounced “blah-say”) aims to improve the astronomical echelle spectroscopy data analysis process through a hybrid data-driven/model-driven approach. It is similar in spirit to Starfish, and wobblé. The key design features of blasé include:

  1. Built on a foundation of pre-computed synthetic stellar spectra, chosen at discrete grid points

  2. Extensibile for a wide range of scientific applications

  3. Handles stellar, telluric, and instrumental features simultaneously

We invite you to engage with us at our GitHub page, with pull requests and discussions welcomed.

This project can use either CPUs or GPUs. To check if you have a GPU available:

import torch


The project currently only supports HPF data, but could be expanded to new spectrographs.
