Fig. 4


Velocity-channel maps of the CO(2–1) line emission after combining the SMA data and the 30-m SD telescope data (see text). The spatial resolution is 3.8′′ × 3.1′′ (HPBW, PA = –51°). The spectra have been binned to a resolution of 2.1 km s-1; marked velocities are expressed in km s-1 and relative to the LSR. The star velocity is V = −26.5 km s-1.
