Maps of ∫T_mbdv of the components contributing to the CS(2−1) emission from Region 2 (see Fig. 3b). Each panel shows the integrated emission ∫T_mbdv of a single Gauss-fit component. Offset (0, 0) as in Fig. 3. Black contours: lowest level and step 0.2 K km s^-1. White contours mark the FWHM levels of the three major peaks in the distribution. a) Integrated emission of the component at  ~ −18.6 km s^-1. b) As a, but for the component at  ~ −19.6 km s^-1.
