Two of the sunspots analyzed in this study, top row: AR 11536 observed on 31 July 2012, bottom row: AR 10953 observed on 2 May 2007. We show maps of the continuum intensity and of the derived geometric height of the log τ = 0 layer across the spots (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 boundary, respectively, as described in the main text.
