Introduction

taurex-emcee is a plugin for the TauREx3.1 atmospheric retrieval framework that extends the choice of sampling methods available to the user. The plugin provides an interface to the emcee sampler, a popular affine-invariant ensemble sampler widely used in the astronomy community. Running the sampler to convergence is automated through the autoemcee package, which also supports MPI parallelization. Thus, the taurex-emcee plugin allows users to easily launch parallelized retrievals of atmospheric spectra with emcee. This enables reliable, efficient, and fast retrievals.
