SolRaT solves the polarized non-LTE radiative transfer problem in solar and stellar atmospheres within the multi-term atom model. The emergent Stokes profiles in the presence of arbitrary magnetic fields are calculated by solving the coupled non-LTE statistical equilibrium and polarized radiative transfer equations. The code includes a set of pre-configured atom models for selected spectral lines including He I D3, and provides a flexible modeling interface for prototyping of polarized non-LTE line formation.
