Fig. 2

Total intensity contour map with apparent polarization B-vectors at 8.46 GHz (combined VLA + Effelsberg) superimposed on the Hα image (from Tüllmann et al. 2000). Contours are plotted at levels (3, 5, 8, 12, 20, 30, 50, 80, 120, 200, 300 and 500) × 13 μJy/b.a. (rms level this frequency). Vectors are proportional to the polarized intensity and indicate apparent B-orientation (10″ corresponds to 100 μJy/b.a.). The resolution is 16″ HPBW.
