Figure 1: Full resolution (HPBW  ) total intensity map of NGC 4594 at 6.2 cm superimposed on the optical photograph of the DSS. The contours are 0.03, 0.06, 0.1, 0.15, 0.3, 1, 6, 20, 50, and 90 mJy/beam. The rms noise in the map is Jy/beam. The orientation of the "vectors'' gives the observed electric field rotated by  , their length is proportional to the observed linearly polarized intensity. The half-power beamwidth is indicated in the bottom left corner.

Figure 5: Full resolution (HPBW  ) map of the linear polarization of NGC 4594 at  cm superimposed on the optical photograph of the DSS. The contours are 20, 30, 40, ... Jy/beam. The rms noise in the map is Jy/beam. The orientation of the "vectors'' gives the observed electric field rotated by as in Figs. 1 and 3, (only their extension is slightly smaller as they are plotted up to the first contour of PI). The length of the vectors is proportional to the degree of linear polarization which is between 20% and 30% in the region of strong linear polarization. The half-power beamwidth is indicated in the bottom left corner.

Figure 6: Linearly polarized intensity of NGC 4594 at  cm observed with the 100-m Effelsberg telescope, superimposed on the optical photograph of the DSS. The contours contours are 160, 250, 350, and 450 Jy/beam. The rms noise in the map is 95 Jy/beam. The orientation of the "vectors'' gives the observed electric field rotated by , their lengths is proportional to the observed linearly polarized intensity. The half-power beamwidth is .

	Figure 8: Smoothed map (HPBW  ) of the total disk emission of NGC 4594 at  cm superimposed on the optical photograph of the DSS. The contours are 50, 100, 250, 500, 1000, ... Jy/beam. The orientation of the "vectors'' gives the intrinsic magnetic field orientation, their length is proportional to the linearly polarized intensity at   cm.
