Comparison of maps of the geometric height of the log τ = 0 layer for selected sunspots inferred using the divergence method from inverted Stokes profiles with and without additional scattered light. From left to right: continuum intensity, z_W without additional scattered light, z_W for additional scattered light with a magnitude of 1% of the mean intensity of the quiet Sun, and z_W for additional scattered light with a magnitude of 2% of the mean intensity of the quiet Sun. The white and black contours indicate the inner and outer penumbral boundaries, respectively. The numbers give the maximum Wilson depression and its mean over the umbra.
