Maps of the continuum intensity and of the derived geometric height of the log τ = 0 layer across the spots analyzed in this study (i.e., the Wilson depression, z_W). From left to right: continuum intensity, z_W derived from the divergence method, z_W derived from the pressure method, and z_W derived from the pressure method degraded to the spatial resolution of the divergence method. The white and black contours indicate the inner and outer penumbral boundaries, respectively.
