Blueshifted (blue contours) and redshifted (red contours) ¹²CO (2–1) (top panel) and ¹³CO (2–1) (bottom panel) averaged emission overlaid on the SMA VEX 1.3 mm continuum emission (grayscale) towards G24. The synthesized beam is at PA = 54° for ¹²CO and at PA = 55° for ¹³CO and is shown in the lower left corner. The emission was averaged in the same velocity intervals as in Fig. 8. Contour levels are 3, 6, 9, 12, 15, 20, and 30 times 1σ, where 1σ is 30 mJy beam^-1 for ¹²CO and ¹³CO. Grayscale contour for the continuum emission is 3σ, where 1σ is 3.2 mJy beam^-1. The crosses mark the positions of the sources identified by Furuya et al. (2002) and Beltrán et al. (2004).
