Abstract. We have analysed two-dimensional spectro-polarimetric data taken with the MSDP observing mode
of THEMIS in the Na I D1 line to investigate the height variation of the magnetic field in sunspot umbrae. From
the Zeeman-induced circular polarization measured at individual MSDP channels within the line profile, maps of
the longitudinal magnetic field have been computed. A method based on Response Functions has been developed
