a) Same as for Fig. 3 but at DBS 78 region (l ~ 301°). Lowest and highest contours are 15 K and 152 K, respectively. Contour spacing is 15 K. b) Radio continuum emission at 1.42 GHz. Lowest and highest contours are 0.018 and 2.6 Jy beam^-1, respectively, without a constant step. Lighter gray color corresponds to the lowest flux value. Dashed pattern circle drawn in the upper left-hand corner indicates the angular resolution of the HI data.
