Top: total intensity (I) image at λ6 cm for G192.8−1.1 (PKS 0607+17) and its surroundings. The “background filtering” technique was used to remove large-scale emission. Contours start at 3.0   mK  T_B (3σ level) and run in steps of 5.0   mK  T_B. The big rectangle area includes the G192.8−1.1, which was used for the TT-plot analysis by excluding the two areas marked by white small rectangles. Middle: PI image of G192.8−1.1 area (PKS 0607+17) at λ6 cm. The same total intensity contours are overlaid as in the top plot. Bars are plotted for observed B-vectors (i.e. PA + 90°) at λ6 cm if . Bottom: infrared image at 60   μm of the same area (Cao et al. 1997) overlaid by λ6 cm I contours.
