SESAMME

SESAMME is a Python package for Simultaneous Estimates of Star-cluster Age, Metallicity, Mass, and Extinction. It uses Bayesian methods to model the integrated-light spectrum of a star cluster, assuming a user-specified set of simple stellar population (SSP) models.

This package uses the emcee framework for its Markov Chain Monte Carlo computations. For additional details on the SESAMME algorithm and a look at its first science applications, see Jones, L. H. et al. 2023.
