Three frames showing the spatial distribution of the derived log₁₀Q values in different horizontal planes above the magnetogram surface. The top panel corresponds to a plane at a height of 110 km, the middle at 1105 km, and the bottom at 2764 km. The blue and red contours denote the negative and positive photospheric magnetic field, respectively at values of B_z = ±50 G. The images are smoothed with a boxcar of width 3 × 3 px².
