FIREFLY is a chi-squared minimisation full fitting code for deriving stellar population properties from spectra. It fits combinations of single-burst stellar population models using the Bayesian Information Criterion and returns light- and mass-weighted ages, metallicities, dust attenuation, stellar mass, and star formation histories.
