CS(5–4) emission (black and gray contours) superimposed on the 870 μm emission. The beam size of CS(5–4) is indicated by the filled circle, while the open circle indicates the APEX beam size. Each plot corresponds to a different V_LSR. The V_LSR of the clumps is indicated in the respective panel. The contours (in units of K km s^-1) for each clump are (lowest (step) highest): (−6.7 km s^-1) 0.19 (0.3) 2.59; (−5.5 km s^-1, C) 0.20 (1.0) 10.20; (−5.5 km s^-1, B) 0.19 (0.5) 3.69; (−4.0 km s^-1) 0.19 (0.7) 4.39; (−2.5 km s^-1) 0.18 (1.0) 8.18; (−1.0 km s^-1) 0.17 (0.2) 1.37; and (+0.2 km s^-1) 0.14 (0.1) 0.74. The lowest contour corresponds to the 3σ level in .
