Taking into account magnetooptical effects, numerical solutions of the transfer equations for the Stokes parameters are obtained; the linearly polarized intensity (U) is calculated; and its monochromatic images of unipolar sunspots are constructed. By comparison with the observational material of the vector magnetograph of the Marshall Space Flight Center, it is found that the model of radial magnetic fields may give rise to U monochromatic images close to those observed. The same conclusion has been obtained previously by Landi Degl'Innocenti (1979), although that analysis was performed with the Milne-Eddington approximation instead of a detailed sunspot model. Moreover, it is shown that the model of spiral magnetic fields leads to results in contrast with observations.
