Velocity integrated CO emission in W33 Main1, W33 A1, W33 B1, W33 B, and W33 Main. The background shows the 230 GHz continuum emission. Blue and red contours correspond to the most blueshifted and redshifted 12CO or C18O emission in the five sources. In W33 Main1, the redshifted and blueshifted emission is integrated over velocity ranges of 3642 km s-1 and 2731 km s-1, respectively (contour levels: 4–23 Jy beam-1 km s-1 in steps of 3 Jy beam-1 km s-1). In W33 A1, the redshifted and blueshifted emission is integrated over velocity ranges of 40–47 km s-1 and 25–32 km s-1, respectively (contour levels: 6–28 Jy beam-1 km s-1 in steps of 3 Jy beam-1 km s-1). In W33 B1, the redshifted and blueshifted emission is integrated over velocity ranges of 40–45 km s-1 and 24–30 km s-1, respectively (contour levels: 5–35 Jy beam-1 km s-1 in steps of 5 Jy beam-1 km s-1). In W33 B, the redshifted and blueshifted emission is integrated over velocity ranges of 64–69 km s-1 and 44–48 km s-1, respectively (contour levels: 10–70 Jy beam-1 km s-1 in steps of 5 Jy beam-1 km s-1). In W33 Main, the redshifted and blueshifted emission (from the IRAM30 m+SMA data) is integrated over 39–42 km s-1 and 28–32 km s-1, respectively (contour levels: 10–25 Jy beam-1 km s-1 in steps of 2.5 Jy beam-1 km s-1). The synthesised beams are shown in the lower left corners of the images.
