Left panel: map of ¹³CO(1–0) integrated intensity for the B5 region obtained by the COMPLETE Survey (Ridge et al. 2006). The orange box shows the area mapped with the GBT. Right panel: integrated intensity map of B5 in NH ₃(1,1). White contours are BOLOCAM dust continuum emission (Enoch et al. 2006), while gray contours show the 0.15 and 0.3 K km s ^-1 levels in NH ₃(1,1) integrated intensity. The young star, B5–IRS1, is shown by the star. The outflow direction is shown by the arrows.
