Molecular outflows detected in CO (2−1) in some sources. The blueshifted and redshifted outflows of CO (2−1) are plotted in blue and red contours, respectively. The contour levels are (−3, 3, 6, 9, 12, 15, 18, 24, 36, 48, 60)×σ, where σ is the rms of the integrated CO emission. The blue and red arrows mark the outflow axes identified in the region. The grayscale images and black contours show SMA 1.3 mm continuum emission. The contour levels are the same as in Fig. 1. The extracted dust condensation is marked by a black cross.
