| Abstract: |
In order to compare vector magnetic fields obtained by two spectral
polarimeters (THEMIS/MTR and Hinode SOT/SP) and two inversion codes
(UNNOFIT and MELANIE), we observed a facular region in the active
region NOAA 10996 on 2008 May 23. We found that they give consistent
results concerning the distributions of field strengths, azimuth and
inclination angles. SOT/SP could resolve small magnetic polarities
with sizes of 1'' to 2'', and detect convergence and divergence
of the horizontal components of magnetic fields in the facular
cells. These findings support the models suggesting the existence of
flux tube bundles in faculae. With this model and multi spectral
line observations, we could infer the relative formation heights of
those spectral lines. |
