Bayesian Estimator for Stellar Population Analysis (BESTA)
BESTA is a Python package for inferring stellar population properties from spectroscopic and/or photometric data using Bayesian inference and Monte Carlo methods.
Full documentation is available at besta.readthedocs.io.
Framework
BESTA is built on top of two core libraries:
- Population Synthesis Toolkit (PST) — flexible stellar population synthesis models.
- CosmoSIS — modular parameter estimation via Monte Carlo sampling.
