UNNOFIT2 inversion code applied for ions Fe i 6301.5 Å,  Fe i 5250.65 Å, and Fe i 6151.62 Å, which are anomalous Zeeman triplet, and the UNNOFIT inversion code applied on ions Cr i 5247.57 Å, Fe i 5250.22 Å, and Fe i 6302.50 Å, which are the normal triplet on the sunspot observed on 17 August 1999 08:53 NOAA 8668 with THEMIS. The longitudinal magnetic field component αB_z is displayed in color (Gauss). The field of view is 160    ×    110 arcsec². The long-slit spectrograph gives a spectrum per acquisition. The entire observation from THEMIS consists of several successive steps of slit-scanning along a direction perpendicular to it, and results in a two-dimensional spatial map (100 scaning steps of the 0.4 arcsec   ×   100 arcsec slit). The interspace between two steps is 0.8 arcsec and the exposure time per frame is 0.3 s. A scan of the region (160    ×    110 arcsec²) took 35 minutes for the six spectral domains.
