Centroid velocity and velocity dispersion distribution of the two-component Gaussian fits of CCH (1–0) hfs lines (ν~87.3 GHz) for clumps MM2, MM3, and C. The upper and lower panels show the two components individually. White contours in left panels follow same definitions as in Figure C.1, representing the integrated intensity map of CCH. In both the upper and lower panels, the gray and green contours and crosses in left and right plot follow the same definitions as in Figure B.1.
