1420 MHz radio continuum and 60 μm images from the CGPS survey. Resolution for both is about 1′. Point-like sources have been removed from the radio continuum image. Circles indicate the approximate inner and outer boundary of the H i shell seen in Fig. 1. The two insets at the bottom of the radio image show a close-up view of G91.56+0.97 and G92.24+1.57 (point-like sources included, see text).
