Continuum intensity maps of the sunspots observed with GRIS. White: manually found intensity contours. Red: contours calculated in B⊥ maps at the value of 1787 gauss (average over all 11 sunspots). ΔP denotes the geometric difference between the two contours. The black arrow points towards disk center. The map in the bottom right corner shows an example of a contour using the average of the Babs values in magenta.
