Spectropolarimetric analysis of the solar Active Region NOAA11005 by inversion techniques: preliminary results.
Abstract
We present the preliminary results of spectropolarimetric observations and analysis of a disk-center region containing a pore. The dataset was acquired on 2008/10/15 by the SOT spectropolarimeter onboard the Solar-B (Hinode) mission. It consists of high spatial and spectral (2.15 pm) resolution full Stokes imaging scans in the iron doublet at 630 nm, in Fast Map Mode (0.3×0.32 arcsec2 pixel scale), with 0.1% polarimetric accuracy. The analysis of a 60×60 pxls2 area around the pore was performed by inversion techniques using the SIR code. We gave in input an initial atmospheric model with a single magnetic component, but accounting for stray light contamination. The code is capable of retrieving the full Stokes syntetized profiles and the inverted atmospheric parameters, like plasma temperature, magnetic field vector etc., for each depth and resolution element. We show and comment the magnetic field reconstruction maps (field strengths and inclinations) as inferred from SIR inversion procedure, comparing to what emerges from the linear polarization maps.
