Forward and Inverse solver for the Radiative Transfer in geometrical height "Z".

The FIRTEZ-DZ inversion code is capable of retrieving, not the average kinematic and magnetic properties like M-E inversion codes do, but rather the full vertical stratification of these physical properties. FIRTEZ-DZ is the only inversion code capable of achieving this in the geometrical scale z instead of the optical depth scale. This is done by combining the radiative transfer equation for polarized light with the magnetohydrostatic momentum equation in ideal magnetohydrodynamics (MHD). The code is under heavily development and currently maintained by Dr. Adur Pastor Yabar and Dr. J. M. Borrero. Original funding for its development was provided by the DFG.

FIRTEZ-DZ is publicly available as free and open software under the GPL2 licence. It can be downloaded/cloned here:

Note: The MHS module is now fully implemented inside of FIRTEZ.

If you use FIRTEZ-DZ in your work/research, we kindly ask that you cite the original paper: Pastor Yabar et al. (2019), A&A, 629, 24. If you use the MHS module as well, please cite Borrero et al. (2021), A&A, 674, 190.
