Maps of synthetic intensity and polarization calculated from a snapshot of the MURaM simulation of a sunspot. The upper panel shows the continuum intensity, and the rest display the Stokes Q, U, and V signals at λ_w = 6301.4 Å, close to the core of the bluer spectral line. All the panels are normalized to the average quiet Sun continuum. The polarization signals are shown on a logarithmic scale for better visualization. Four symbols mark the location of the profiles shown in Fig. 2.
