Left: total emission (contours) at λ6.2 cm (VLA+Effelsberg) at 25′′ resolution, overlaid onto a greyscale presentation (in arbitrary units) of the infrared map at 22 μm from the WISE telescope (Wright et al. 2010) at 17′′ resolution, kindly provided by Seppo Laine. Right: total emission (contours) at λ3.5 cm (VLA only) at 12′′ resolution, overlaid onto a greyscale presentation (in arbitrary units) of the infrared map at 8 μm from the IRAC camera of the Spitzer telescope at 2′′ resolution (Fazio et al. 2004). The radio map is incomplete in the north-eastern and south-western corners.
