Total intensity map at 8.35 GHz (contours)with polarization observed with the 100-m Effelsberg telescope, superimposed on the Hα image (from Tüllmann et al. 2000). The contour levels are (3, 5, 8, 12, 20, 30, 50)  ×  400 μJy/b.a. (rms). The vectors show the apparent B-orientation, their lengths are proportional to the polarized intensity (1′ corresponds to 1.2 mJy/b.a.). The angular resolution is 84″ HPBW.
