Maps of ∫T_mbdv of the various components contributing to the ¹³CO(1−0) emission from Region 2 (see Fig. 3b). Each panel shows the integrated emission ∫T_mbdv of a single Gaussian component. Offset (0, 0) as in Fig. 3. Black contours: lowest levels 0.5, 1, and 2 K km s^-1, then in steps of 2 K km s^-1. For clarity, the 1 K km s^-1 contour is drawn dashed; the white polygons in panels b) and c) indicate the FWHM contours of the corresponding Gaussian component of the CS(2−1) emission (see text and Fig. 10). a) Integrated emission of the component between  − 17 and  − 18 km s^-1. b) As a, but for the component between  − 18 and  − 19 km s^-1. c) As a, for the component between  − 19 and  − 20 km s^-1. d) As a, for the component between  − 20 and  − 21 km s^-1. e) As a, for the component between  − 21 and  − 22 km s^-1.
