Caption
Variation of Stokes-V profiles of Fe I (5250.2 Å and 6302.5 Å) emerging from a small region on either side of the magnetic flux sheet (strong field strength). The effects of refraction of the fast (predominantly magnetic) wave is visible in the Stokes-V asymmetries and zero-crossing shift as a function of time.
