Sažetak

A high-resolution 3-dimensional model of the photospheric magnetic field is essential for the investigation of small-scale
solar magnetic phenomena. The SIR code is an advanced Stokes-inversion code that deduces physical quantities, e.g. magnetic
field vector, temperature, and LOS velocity, from spectropolarimetric data. We extended this code by the capability of directly
using large data sets and inverting the pixels in parallel. Due to this parallelization it is now feasible to apply the code
directly on extensive data sets. Besides, we included the possibility to use different initial model atmospheres for the
inversion, which enhances the quality of the results.
