David McKenzie and Ken Kobayashi (ST13) are co-authors on a manuscript recently accepted for publication in The Astrophysical Journal, entitled “Tomography of a Solar Plage with the Tenerife Inversion Code”. The paper reports progress in analyzing the spectropolarimetric observations obtained by the Chromospheric LAyer SpectroPolarimeter (CLASP2) sounding rocket mission. These unprecedented data consist of full Stokes profiles in the spectral region around the Mg II h and k lines for a single slit position, with around two thirds of the 200 arcsec slit crossing a plage region and the rest crossing an enhanced network. An earlier analysis of these data allowed us to infer the longitudinal component of the magnetic field by applying the weak field approximation (WFA) to the circular polarization profiles, and to assign the inferred magnetic fields to different layers of the solar atmosphere. In this work, we apply the recently developed TIC to the same data. We obtain a stratified model atmosphere that fits the intensity and circular polarization profiles at each position along the spectrograph slit and we compare our results for the longitudinal component of the magnetic field with the previously obtained WFA results.
