Description
The physical interpretation of spectropolarimetric observations of lines
of neutral helium, such as those of the 10830 Å multiplet,
represents an excellent opportunity for investigating the magnetism of
plasma structures in the solar chromosphere. Here we present a powerful
forward modeling and inversion code that permits either to calculate the
emergent intensity and polarization for any given magnetic field vector
or to infer the dynamical and magnetic properties from the observed
Stokes profiles. This diagnostic tool is based on the quantum theory of
spectral line polarization, which self-consistently accounts for the
Hanle and Zeeman effects in the most general case of the incomplete
Paschen-Back effect regime. We also take into account radiative transfer
effects. An efficient numerical scheme based on global optimization
methods has been applied. Our Stokes inversion code permits a fast and
reliable determination of the global minimum.
