Representative Stokes profiles at three different locations in the diffraction limited observations. The three locations are: penumbra (green), umbra (blue), umbral flash (red). The points display the observed data whereas solid lines correspond to the fitted profiles. The profiles are normalized to the quiet sun continuum and to better visualize the data, vertical shifts have been applied. These are: [ + 0.2, 0, −0.2] in Stokes I and [ + 0.02, 0, −0.02] in Stokes Q, U and V. In addition, Stokes I signals in the umbra (blue) and umbral flash (red) have been multiplied by a factor of 2 before the shift is applied to better display the variations.
